Turtle Moon transports the listener to Verity, Florida, a place where anything can happen during the month of May, when migrating sea turtles come to town, mistaking the glow of the streetlights for the moon.A young single mother is murdered in her apartment and her baby is gone. Keith, a 12-year-old boy in the same apartment building - the self-styled "meanest boy" in town - also disappears.
In pursuit of the baby, the boy and the killer, are Keith's divorced mother and a cop who himself was once considered the meanest boy in town. Their search leads them down the humid byways of a Florida populated almost exclusively by people from somewhere else; emotional refugees seeking sanctuary along the swampy coast.
