Book cover for How The Internet Happened: From Netscape to the iPhone

The internet was never intended for you, opines Brian McCullough in this lively narrative of an era that utterly transformed everything we thought we knew about technology. In How the Internet Happened, he chronicles the whole fascinating story for the first time, beginning in a dusty Illinois basement in 1993, when a group of college kids set off a once-in-an-epoch revolution with what would become the first “dotcom.”


Depicting the lives of now-famous innovators like Netscape’s Marc Andreessen and Facebook’s Mark Zuckerberg, McCullough also reveals surprising quirks and unknown tales as he tracks both the technology and the culture around the internet’s rise. Cinematic in detail and unprecedented in scope, the result both enlightens and informs as it draws back the curtain on the new rhythm of disruption and innovation the internet fostered, and helps to redefine an era that changed every part of our lives.

Book cover for Broad Band

Women are not ancillary to the history of technology; they turn up at the very beginning of every important wave. But they’ve often been hidden in plain sight, their inventions and contributions touching our lives in ways we don’t even realize.

Author Claire L. Evans finally gives these unsung female heroes their due with her social history of the Broad Band, the women who made the internet what it is today. Learn from Ada Lovelace, the daughter of Lord Byron, who wove numbers into the first program for a mechanical computer in 1842. Seek inspiration from Grace Hopper, the tenacious mathematician who democratized computing by leading the charge for machine-independent programming languages after World War II. Meet Elizabeth “Jake” Feinler, the one-woman Google who kept the earliest version of the Internet online, and Stacy Horn, who ran one of the first-ever social networks on a shoestring out of her New York City apartment in the 1980s. Evans shows us how these women built and colored the technologies we can’t imagine life without.

Join the ranks of the pioneers who defied social convention and the longest odds to become database poets, information-wranglers, hypertext dreamers, and glass ceiling-shattering dot com-era entrepreneurs.

Book cover for Fire Cannot Kill A Dragon

The official, definitive oral history of the blockbuster show from Entertainment Weekly‘s James Hibberd, published with HBO’s official support.

It was supposed to be impossible. George R.R. Martin was a frustrated television writer who created his bestselling A Song of Ice and Fire fantasy novels to be an unfilmable saga bound only by the limits of his vast imagination. Then a pair of first-time TV writers teamed with HBO to try and adapt Martin’s epic. We’ve all seen the eight seasons of the Emmy-winning fantasy series that came next. But there is one Game of Thrones tale that has yet to be told: the 13-year behind-the-scenes struggle to pull off this extraordinary phenomenon.

In All Men Must Die, award-winning Entertainment Weekly writer James Hibberd chronicles the untold story of Game of Thrones, from the creative team’s first meetings to staging the series finale and all the on-camera battles and off-camera struggles in between. The book draws from more than 50 revealing new interviews, rare and stunning photos, and unprecedented access to the producers, cast, and crew who took an impossible idea and made it into the biggest show in the world.

Book cover for Shadow Moon

From two of the greatest imaginations of our time comes a magnificent novel of adventure and magic…SHADOW MOON: First in the Chronicles of the Shadow War.

The genius of Star Wars(r) creator George Lucas and the vision of Chris Claremont, the author of the phenomenally bestselling The Uncanny X-Menadventures, merge in what must be the fantasy event of the year.

In Shadow Moon, war and chaos have gripped the land of Tir Asleen. An ancient prophecy reveals one hope: a savior princess who will ascend to the throne when the time is right.  But first, a Nelwyn wanderer must face forces of unimaginable malevolence and dangerous, forbidden rites of necromancy that
could bring back a powerful warrior from soulless sleep.

George Lucas reshaped filmmaking in the ’70s and ’80s with his Star Wars and Indiana Jones films.  When Bantam Books asked Lucas if he had any stories he would like to develop as novels rather than as films, Lucas turned to his 1988 fantasy film, Willow.  

“When I wrote the story for Willow, I began with the pre-story,” Lucas said, “but the full story was yet to be told.”  

Now, Lucas’s vision is being fulfilled with the talented help of Chris Claremont. Having previously taken the reins of what was for a decade the bestselling comic in the western hemisphere (The Uncanny X-Men) Claremont assumes the responsibility of foster parent to Lucas’s creation.

Book cover for Shadow Dawn

From George Lucas, creator of Star Wars(r) and Indiana Jones, and Chris Claremont, author of the bestselling X-Men adventures, comes the thrilling sequel to “Shadow Moon,” taking readers deeper into a stunningly original world of magic, myth, and legend.


The momentous Ascension of Princess Elora Danan should have brought peace to the Thirteen Realms. Instead, an intense Shadow War rages, spearheaded by the evil Mohdri. He has dispatched his dread Black Rose commando assassins to capture Elora and her sworn protector, Thorn Drumheller. But Mohdri himself is just a facade for a more dangerous entity: the Deceiver. But who–or what–is the Deceiver? And how can Elora, Thorn, and their ragtag band defeat this unspeakable force? The answer lies in a perilous journey to a land undisturbed since the dawn of time. A journey that will end at the unbreachable citadel of the dragon, where a chilling betrayal will change the fate of Elora, Thorn, and the Thirteen Realms forever.

Book cover for The Age of Surveillance Capitalism

The challenges to humanity posed by the digital future, the first detailed examination of the unprecedented form of power called “surveillance capitalism,” and the quest by powerful corporations to predict and control our behavior.

In this masterwork of original thinking and research, Shoshana Zuboff provides startling insights into the phenomenon that she has named surveillance capitalism. The stakes could not be higher: a global architecture of behavior modification threatens human nature in the twenty-first century just as industrial capitalism disfigured the natural world in the twentieth.

Zuboff vividly brings to life the consequences as surveillance capitalism advances from Silicon Valley into every economic sector. Vast wealth and power are accumulated in ominous new “behavioral futures markets,” where predictions about our behavior are bought and sold, and the production of goods and services is subordinated to a new “means of behavioral modification.”

The threat has shifted from a totalitarian Big Brother state to a ubiquitous digital architecture: a “Big Other” operating in the interests of surveillance capital. Here is the crucible of an unprecedented form of power marked by extreme concentrations of knowledge and free from democratic oversight. Zuboff’s comprehensive and moving analysis lays bare the threats to twenty-first century society: a controlled “hive” of total connection that seduces with promises of total certainty for maximum profit–at the expense of democracy, freedom, and our human future.

With little resistance from law or society, surveillance capitalism is on the verge of dominating the social order and shaping the digital future–if we let it.

Cover for Digital Minimalism: Choosing a Focused Life In A Noisy World

Georgetown computer scientist Cal Newport’s Deep Work sparked a movement around the idea that unbroken concentration produces far more value than the electronic busyness that defines the modern work day. But his readers had an urgent follow-up question: What about technology in our personal lives?

In recent years, our culture’s relationship with personal technology has transformed from something exciting into something darker. Innovations like smartphones and social media are useful, but many of us are increasingly troubled by how much control these tools seem to exert over our daily experiences–including how we spend our free time and how we feel about ourselves.

In Digital Minimalism, Newport proposes a bold solution: a minimalist approach to technology use in which you radically reduce the time you spend online, focusing on a small set of carefully-selected activities while happily ignoring the rest.

He mounts a vigorous defense for this less-is-more approach, combining historical examples with case studies of modern digital minimalists to argue that this philosophy isn’t a rejection of technology, but instead a necessary realignment to ensure that these tools serve us, not the other way around.

To make these principles practical, he takes us inside the growing subculture of digital minimalists who have built rich lives on a foundation of intentional technology use, and details a decluttering process that thousands have already used to simplify their online lives. He also stresses the importance of never clicking “like,” explores the underappreciated value of analog hobbies, and draws lessons from the “attention underground”–a resistance movement fighting the tech companies’ attempts to turn us into gadget addicts.

Digital Minimalism is an indispensable guide for anyone looking to reclaim their life from the alluring diversions of the digital world.

Cover for The Lives They Left Behind

When Willard State Hospital closed its doors in 1995, after operating as one of New York State’s largest mental institutions for over 120 years, a forgotten attic filled with suitcases belonging to former patients was discovered. Using the possessions found in these suitcases along with institutional records and doctors’ notes from patient sessions, Darby Penney, a leading advocate of patients’ rights, and Peter Stastny, a psychiatrist and documentary filmmaker, were able to reconstruct the lives of ten patients who resided at Willard during the first half of the twentieth century.

The Lives They Left Behind tells their story. In addition to these human portraits, the book contains over 100 photographs as well as valuable historical background on how this state-funded institution operated. As it restores the humanity of the individuals it so poignantly evokes, The Lives They Left Behind reveals the vast historical inadequacies of a psychiatric system that has yet to heal itself.

This impossible-to-put-down tale leads readers on an unforgettable journey—fraught with danger yet filled with mystical and magical moments.

Cover for The Republic of Pirates

The untold story of a heroic band of Caribbean pirates whose defiance of imperial rule inspired revolt in colonial outposts across the world. In the early eighteenth century, the Pirate Republic was home to some of the great pirate captains, including Blackbeard, “Black Sam” Bellamy, and Charles Vane. Along with their fellow pirates—former sailors, indentured servants, and runaway slaves—this “Flying Gang” established a crude but distinctive democracy in the Bahamas, carving out their own zone of freedom in which servants were free, blacks could be equal citizens, and leaders were chosen or deposed by a vote. They cut off trade routes, sacked slave ships, and severed Europe from its New World empires, and for a brief, glorious period the Republic was a success.

Cover for The Sex Lives of Cannibals

At the age of twenty-six, Maarten Troost who had been pushing the snooze button on the alarm clock of life by racking up useless graduate degrees and muddling through a series of temp jobs decided to pack up his flip-flops and move to Tarawa, a remote South Pacific island in the Republic of Kiribati. He was restless and lacked direction, and the idea of dropping everything and moving to the ends of the Earth was irresistibly romantic. He should have known better. The Sex Lives of Cannibals tells the hilarious story of what happens when Troost discovers that Tarawa is not the island paradise he dreamed of. Falling into one amusing misadventure after another, Troost struggles through relentless, stifling heat, a variety of deadly bacteria, polluted seas, toxic fish, and worst of all, no television or coffee. And that’s just the first day. Sunburned, emaciated, and stinging with sea lice, Troost spends the next two years battling incompetent government officials, alarmingly large critters, erratic electricity, and a paucity of food options. He contends with a cast of bizarre local characters, including “Half-Dead Fred” and the self-proclaimed Poet Laureate of Tarawa (a British drunkard who’s never written a poem in his life), and eventually settles into the ebb and flow of island life, just before his return to the culture shock of civilization. With the rollicking wit of Bill Bryson, the brilliant travel exposition of Paul Theroux, and a hipster edge that is entirely Troost’s own, The Sex Lives of Cannibals is the ultimate vicarious adventure. Readers may never long to set foot on Tarawa, but they’ll want to travel with Troost time and time again.

Book cover for Blackout

Rise up while you can. -Georgia Mason

The year was 2014. The year we cured cancer. The year we cured the common cold. And the year the dead started to walk. The year of the Rising.

The year was 2039. The world didn’t end when the zombies came, it just got worse. Georgia and Shaun Mason set out on the biggest story of their generation. They uncovered the biggest conspiracy since the Rising and realized that to tell the truth, sacrifices have to be made.

Now, the year is 2041, and the investigation that began with the election of President Ryman is much bigger than anyone had assumed. With too much left to do and not much time left to do it in, the surviving staff of After the End Times must face mad scientists, zombie bears, rogue government agencies-and if there’s one thing they know is true in post-zombie America, it’s this:

Things can always get worse.

Blackout is the conclusion to the epic trilogy that began in the Hugo-nominated Feed and the sequel, Deadline.

Book cover for Small Pieces Loosely Joined

In this insightful social commentary, David Weinberger goes beyond misdirected hype to reveal what is truly revolutionary about the Web. Just as Marshall McLuhan forever altered our view of broadcast media, Weinberger shows that the Web is transforming not only social institutions but also bedrock concepts of our world such as space, time, self, knowledge-even reality itself. Through stories of life on the Web, a unique take on Web sites, and a pervasive sense of humor, Weinberger is the first to put the Web into the social and intellectual context we need to begin assessing its true impact on our lives. The irony, according to Weinberger, is that this seemingly weird new technology is more in tune with our authentic selves than is the modern world. Funny, provocative, and ultimately hopeful, Small Pieces Loosely Joined makes us look at the Web as never before.

Book cover for Deadline

Now, Shaun hits the road to find what truth can be found at the end of a shotgun.

Book cover for Team Human

Team Human is a manifesto—a fiery distillation of preeminent digital theorist Douglas Rushkoff’s most urgent thoughts on civilization and human nature. In one hundred lean and incisive statements, he argues that we are essentially social creatures, and that we achieve our greatest aspirations when we work together—not as individuals. Yet today society is threatened by a vast antihuman infrastructure that undermines our ability to connect. Money, once a means of exchange, is now a means of exploitation; education, conceived as way to elevate the working class, has become another assembly line; and the internet has only further divided us into increasingly atomized and radicalized groups.


Team Human delivers a call to arms. If we are to resist and survive these destructive forces, we must recognize that being human is a team sport. In Rushkoff’s own words: “Being social may be the whole point.” Harnessing wide-ranging research on human evolution, biology, and psychology, Rushkoff shows that when we work together we realize greater happiness, productivity, and peace. If we can find the others who understand this fundamental truth and reassert our humanity—together—we can make the world a better place to be human.

After a lifetime of bottling up his magical powers, Harry finally feels like a normal kid. But even within the Wizarding community, he is special.

Though Harry’s first year at Hogwarts is the best of his life, not everything is perfect.

The war against Voldemort is not going well: even Muggle governments are noticing. Ron scans the obituary pages of The Daily Prophet looking for familiar names. Dumbledore is absent from Hogwarts for long stretches of time, and the Order of the Phoenix has already suffered losses.

And yet …

As in all wars, life goes on. Sixth-year students learn to Apparate, and lose a few eyebrows in the process. The Weasley twins expand their business. Teenagers flirt and fight and fall in love. Classes are never straightforward, though Harry receives some extraordinary help from the mysterious Half-Blood Prince.

So it’s the home front that takes center stage in the multilayered sixth installment of the story of Harry Potter. Here at Hogwarts, Harry will search for the full and complex story of the boy who became Lord Voldemort – and thereby find what may be his only vulnerability.

Harry Potter and the Order of the Phoenix

It’s official: the evil Lord Voldemort has returned. His influence is suddenly everywhere in the Wizarding world, and his former allies, the Death Eaters, are returning to his side in droves. In response, the Order of the Phoenix, which worked to stop him during his last rise to power, has reconvened. This time, all of the adults Harry trusts have joined in. And even though Harry is at the center of many of their plans—Voldemort is intent on killing him, after all—they want so badly to protect him that they are keeping him completely out of the loop.

Problems are cropping up at Hogwarts, too, where government officials are meddling in just about everything. And just because Voldemort and the Death Eaters are threatening open warfare does not mean that fifth-year students get out of their exams. Meanwhile, Harry’s powerful connection to Voldemort seems to be growing even stronger, as he realizes that he has direct access to the Dark Lord’s mind. It’s time for Harry and his friends to take drastic action, but the course they choose will have terrible unforeseen consequences.
