The hunt / Faye Kellerman.

Peter and his partner, Detective Tyler McAdams, are thrown into an unsolved case and propelled into action when a body is found in Upstate New York, in the very woods where a man previously went missing. But that's not the only crisis that Peter has to deal with. Teresa McLaughlin, the biological mother of Peter and Rina's foster son, Gabe, has fled to Los Angeles with her two other children in tow, hoping to avoid a court injunction amid a messy divorce. But L.A. is no escape from her problems--she is found by ruthless men and beaten mercilessly. When Terry wakes, barely conscious, she discovers that both of her children are gone and frantically calls Gabe for help. Unable to assist his mother immediately, Gabe enlists the help of Peter and Rina and contacts his biological father, the notorious Christopher Donatti, a former hit man from a known crime family who's now a multi-millionaire in Nevada. By bringing Donatti into the fray, Gabe, Peter, and Rina know they have made a deal with the devil--but with Terry on the verge of death, they have no choice. As these unlikely allies rally to find the kidnappers of Terry's children before things end tragically, they race headlong toward an explosive confrontation from which no one will emerge unscathed.
