For Mack McKinley and his team of GhostWalker killing machines, urban warfare is an art. But despite a hard-won knowledge of the San Francisco streets, Mack knows from experience that too many things can still go wrong. Danger was just another part of the game - and now he´s come face-to-face with a woman who can play just as tough. She´s Jaimie, a woman with a sapphire stare so potent it can destroy a man. Years ago she and Mack had a history - volatile, erotic and electric. Then she vanished. But now she´s walked back into Mack´s life again, as a spy with more secrets than are good for her. Against all odds, she´s hooking up with Mack one more time to take on an enemy that could destroy them both, or bring them back together in one hot, no-holds-barred adrenaline rush.
