Atlee Pine, an FBI special agent, 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.

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.

Includes an excerpt from David Baldacci's new novel Long road to mercy (pages 421-448).

"For her entire life, FBI agent Atlee Pine has been searching for her twin sister, Mercy, who was abducted at the age of six and never seen again. Mercy's disappearance left behind a damaged family that later shattered beyond repair when Atlee's parents inexplicably abandoned her. Now, after a perilous investigation that nearly proved fatal, Atlee has finally discovered not only the reason behind her parents' abandonment and Mercy's kidnapping, but also the most promising breakthrough yet: proof that Mercy survived her abduction and then escaped her captors many years ago. Though Atlee is tantalizingly close to her family at last, the final leg of her long road to Mercy will be the most treacherous yet. Mercy left at least one dead body behind before fleeing her captors years before. Atlee has no idea if her sister is still alive, and if so, how she has been surviving all this time. When the truth is finally revealed, Atlee Pine will face the greatest danger yet, and it may well cost her everything"--
