The Girl in the Woods by Gregg Olsen
Kitsup County forensic pathologist Birdy Waterman is well known for giving a voice to the voiceless: the corpses of people who are often victims of violent crimes. Birdy is also letting her teenage nephew Sean stay with her for a while but the family reunion is put on hold when Birdy gets a phone call from the coroner's office. An unidentified foot has been found in Banner Forest. The only clue to its owner: pink nail polish on the toenails. As Birdy teams up with homicide detective Kendall Stark to investigate, she soon discovers that people all over town are hiding secrets that can prove deadly if they are uncovered.
