(Book)

Series information from Fantastic Fiction.

This waterfowl season, the hunters become the hunted. Newly promoted sheriff's deputy Delia Chavez has worked hard to get where she is. Without any family to speak of, law enforcement is all she has. But just a few days into her new job, Delia finds the body of a hunter washed up on the bank of the Willamette River missing his trigger finger. Soon, more bodies are found--all hunters without their trigger fingers. Facing evasive killers who stop at nothing to conceal their crimes, Delia must bring the criminals to justice because everyone knows, if you're not the predator, you're the prey.
