In the northern Californian town of Coventry, two teenage brothers go into the woods one day; only one comes back. No one knows what happened to the younger brother, Josh, until the older brother, Oren, now an ex-investigator for the Army Criminal Investigations Division, returns home after twenty years.

His first morning back, he hears a thump on the front porch. Lying in front of the door is a human jawbone, teeth still intact. It is not the first such object, his father tells him. Other remains have been left there as well.

Josh is coming home.... bone by bone.

Using all his investigative skills, and delving into the dark heart of Coventry, a place full of secrets and secret-keepers, Oren sets out to uncover the truth that has haunted the town for twenty years.
