Keeping Watch — Laurie R. King

Allen Carmichael came back from Vietnam a lifetime ago--but only now was he ready to return home. For years, he's lived on the fringes of the law, using a soldier's skills to keep watch over those too young to defend themselves. Some consider him nothing but a kidnapper for hire--the best in the business; others call him a hero. His specialty has been rescuing children from abusive parents and escorting them to loving homes. But after twenty-five years, he is ready to take on his final case--a case that could destroy him.

The boy's name is Jamie: He believes his father is going to kill him. Allen is convinced that the twelve-year-old is right and devises a strategy to save him. His last job done, Allen heads back to Folly Island, where he plans to settle into a quiet life. But not long after his return, a small plane piloted by the boy's father's crashes, leaving behind debris--but no body. Now it is up to Allen to resolve whether Jamie's father is dead or alive--and to make sure Jamie himself stays out of harm's way. But a series of ominous events leads Allen to question whether Jamie's father is really the enemy after all. Or if the real threat is far more unspeakable...and the killer unimaginable.
