Book Description
On the trail of a serial killer, the path splits in two...

FBI special agent Kelly Jones has worked on many disturbing cases in her career, but nothing like this. A mass grave site unearthed on the Appalachian Trail puts Kelly at the head of an investigation that crosses the line--from Massachusetts to Vermont, from wealthy vacationers to poor transients, from a serial killer to a copycat nemesis.

Assisted by law enforcement from both states and a forensic anthropologist, Kelly searches for the killers. But as darkness falls, another victim is taken. Kelly must race to save him before he joins the rest...in the boneyard.
