The first book in the Waverly series

Ex-con and professional poker player Timothy Waverly travels to Traverse City, Michigan for a break...and falls into bed with a seductress named Midnight. She's an out-of-towner, too, there to rescue her self-destructive brother, who has stupidly ripped off a fortune in cocaine from a vicious Chicago mobster. Now she is being chased by Shadow, a hemorrhoidal hitman who gleefully specializes in torture and rape, and Gleep, his muscle-bound henchman. The odds are stacked against her, but Waverly is a gambler who knows how to play them...
