Long Road to Mercy

Atlee Pine, an FBI special agent assigned to the remote wilds of the western United States. Ever since her twin sister was abducted by a notorious serial killer at age five, Atlee has spent her life hunting down those who hurt others. And she's the best at it. She could be one of the Bureau's top criminal profilers, if she didn't prefer catching criminals in the vast wilderness of the West to climbing the career ladder in the D.C. office. Her chosen mission is a lonesome one--but that suits her just fine. Now, Atlee is called in to investigate the mutilated carcass of a mule found in the Grand Canyon--and hopefully, solve the disappearance of its rider. But this isn't the only recent disappearance. In fact, it may be just the first clue, the key to unraveling a rash of other similar missing persons cases in the canyon.
