In this action-packed techno-thriller, a routine computer cleanup sets off an electrifying quest for an enigmatic-and deadly-treasure. After selling his dorm-room startup for millions and effectively retiring at the age of twenty-five, Alex Fife is eager for a new challenge. When he agrees to clean up an old PC as a favor, he never expects to find the adventure of a lifetime waiting for him inside the machine. But as he rummages through old emails, Alex stumbles upon a startling discovery: The previous owner, a shady antiques smuggler, had been trying to unload a mysterious object known as the Florentine on the black market. And with the dealer's untimely passing, the Florentine is now unaccounted for and ripe for the taking. Alex dives headfirst into a hunt for the priceless object.   What starts out as a seemingly innocuous pursuit quickly devolves into a nightmare when Alex discovers the true technological nature of the Florentine. Not just a lost treasure, it's something far more insidious: a weapon that could bring the developed world to its knees. Alex races through subterranean grottos, freezing morgues, and hidden cellars in the dark underbelly of Los Angeles, desperate to find the Florentine before it falls into the wrong hands. Because if nefarious forces find it first, there'll be nothing Alex-or anyone else-can do to prevent a catastrophic attack.   Leading security specialist Carey Nachenberg delivers expert technical details in this gripping, highly entertaining cyber thrill ride-perfect for fans of Neal Stephenson and William Gibson.
