Software billionaire Marc Julian's orderly life is shattered one night by a cyber-intrusion into his company's servers. He's always surrounded himself with the best people, but finding the culprit behind this might require a real expert...and sometimes it takes a thief to catch a thief.

Jesse Winchester and his team of "grey hat" hackers are suddenly available to Marc. Marc doesn't know if he should trust Jesse with the keys to his company's kingdom. After all, Jesse's a convicted felon, sent to prison for violating the Computer Fraud and Abuse Act. A felon sentenced to 35 years in prison, who mysteriously served only three years before being released.

Marc's first company, his whole life, was shattered because he trusted the wrong person. This time there's even more at stake, but few other options. Especially when his evil enemies, the billionaire industrialist Krom brothers, are revealed to be the source of the intrusion.

Is Jesse there to help Marc or does he have his own history with the Kroms, his own score to settle? As Jesse and Marc spend more time together, their growing intimacy is at war with their need to win their respective battles. Soon the game they start to play with each other, against each other, becomes more exciting, more exquisitely frustrating, and more dangerous.
