Daniel Suarez's New York Times bestselling debut high-tech thriller is "so frightening even the government has taken note" (Entertainment Weekly).

Daemons are small computer programs that run silently in the background, waiting for a specific event or time to activate. Only then do they carry out their intended purpose. From printing to buying and selling stocks and much more, they make our networked world possible. But they also make it vulnerable...
When the obituary of legendary computer game architect Matthew Sobol appears online, a previously dormant daemon activates, initiating a chain of events that begins to unravel our interconnected world. This daemon reads news headlines, recruits human followers, and orders assassinations. With Sobol’s secrets buried with him, and as new layers of his daemon are unleashed, it’s up to Detective Peter Sebeck to stop a self-replicating virtual killer before it achieves its ultimate purpose. And to do so, he must uncover what that purpose is...

From Publishers Weekly

Oct 06, 2008 – Originally self-published, Suarez's riveting debut would be a perfect gift for a favorite computer geek or anyone who appreciates thrills, chills and cyber suspense. Gaming genius Matthew Sobol, the 34-year-old head of CyberStorm Entertainment, has just died of brain cancer, but death doesn't stop him from initiating an all-out Internet war against humanity. When the authorities investigate Sobol's mansion in Thousand Oaks, Calif., they find themselves under attack from his empty house, aided by an unmanned Hummer that tears into the cops with staggering ferocity. Sobol's weapon is a daemon, a kind of computer process that not only has taken over many of the world's computer systems but also enlists the help of superintelligent human henchmen willing to carry out his diabolical plan. Complicated jargon abounds, but most complexities are reasonably explained. A final twist that runs counter to expectations will leave readers anxiously awaiting the promised sequel.

Customer Reviews

This is book ONE of a two book series!

Excellent book!! The target audience for this is definitely gamers, computer programmers, and techies but anyone who likes a fast paced action thriller will enjoy this.

Please keep in mind that this is a two book series. After you finish reading Daemon, go pick up Freedom-TM for the conclusion!

Outstanding Potential...Awful Follow-Through

The Good: The plot has an excellent premise, the background elements and description are solid, and the technical references and concepts are both accurate and intriguing. There are enough subplots and intertwined events to make it a real page-turner. And, most gratifyingly, unlike many novels over the past decade, both the character development and dialog are strong and believable. I was really drawn into the story.

The Bad: The book is only 80 percent complete! At the end of the book there are so many unanswered questions, loose threads and dangling subplots that you're left gasping for a sequel---or at least a two paragraph epilogue. It's like the writer reached the last chapter and decided that he'd done enough to get it published so he gave it a limp, half-hearted last minute wrap-up. I almost wish that the whole book had been poorly written so that I wasn't left so empty handed at the end.

Daemon is worth reading, so long as you keep your expectations low as you move through it. You WILL be left unfulfilled.


This book is amazing! For the reviewer who was disappointed in the ending and thought that it left many questions unanswered, there is a sequel titled "Freedom".
