Deal Breaker by Harlan Coben

Pretty good, fluffy entertainment. Sports agent Myron Bolitar is poised on the edge of the big time. So is Christian Steele, a rookie quarterback and Myron's prized client. But when Christian gets a phone call from a former girlfriend, a woman who everyone, including the police, believes is dead, the deal starts to go sour. Trying to unravel the truth about a family's tragedy, a woman's secret, and a man's lies, Myron is up against the dark side of his business--where image and talent make you rich, but the truth can get you killed.
