Charli Riven, a prototypical Gen-Xer who works hard and plays harder, is known as CharliX to the Consortium, an elite community of coders, hackers, and crackers. She thinks out of the box, manipulates code, and makes money hand over fist for the hedge funds her employer manages. When she's not shattering glass ceilings and showing the code-boys how it's done, Charli turns her relentless focus to surfing the Atlantic—and to Anna Pendleton, her brilliant colleague, the only woman she's ever trusted, in or out of bed. What Charli doesn't know is that Anna is a CIA plant, hot on the trail of a rogue agent, John Romello. And neither of them knows that Charli is the object of Romello's quest, that he believes she and other Gen-Xers hold the genetic key to his new world order. When the system is breached and the waves begin to collapse around them, will Charli and Anna solve for X in time?
