Book excerpt: #1 New York Times bestselling author Christine Feehan goes beyond the boundaries of paranormal romance as two lovers take to the streets to play the most dangerous game of all. 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 is just another part of the game—and now he’s come face-to-face with a woman who can play just as tough. Jaimie is 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. Now she’s walked back into Mack’s life as a spy with too many secrets for her own good. 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.
