Publishers Weekly Starred Review:

Originally self-published, Daniel 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.

See also, Gold Bug Variations, by Richard Powers:

Despite occasional bewilderment at arid patches of scientific jargon and interminable displays of arcane knowledge for its own sake, a reader persists with The Gold Bug Variations (the title, obviously, is a play on Bach's Goldberg Variations , which have a key role in the book's intellectual structure, and Edgar Allan Poe's The Gold Bug , about the solving of a puzzle). For there is a perpetual air of surprise about the book, of intellectual excitement, a passionate involvement with words that expands into delightfully witty dialogue and profoundly evocative description. Reading it is hard work, but it's also deeply enriching; the decade is not likely to bring another novel half as challenging and original.
