Girl, Undone (Ella Dark #29)

FBI Agent Ella Dark has studied serial killers from the time she could read, devastated by the murder of her own father, and has gained an encyclopedic knowledge of murderers.

A string of murders linked only by the haunting keepsakes taken from their homes plunges FBI Agent Ella Dark into the world of a trophy-obsessed killer.

With each relative of an unresolved murder falling prey, Ella must decode the twisted logic behind the collection or risk becoming a trophy herself.
