This Wretched Valley by Jenny Kiefer is a horror story.
The book begins by describing a crime scene with a skeleton and two horribly mutated bodies. Investigators are stumped.
Then it backtracks to the events leading up to the grisly scene. A foursome plans a hiking trip into a remote area of Kentucky. Clay and Sylvia are participating to complete grad research in an uncharted area. Dylan is an up and coming rock climber looking to impress her new sponsor by climbing in a new location. Her boyfriend Luke and his dog round out the group.
The trip starts to go terribly wrong. The area is eerily quiet, seemingly devoid of all life. Luke’s dog goes missing. Then he becomes badly injured. The group realizes they are in trouble when they are unable to find their way back to their car.
The place is rampant with the ghosts of previous victims. All subject to the evil of the place which gradually affects every member of their group.
This was a good change of pace with a creepy storyline a bit reminiscent of The Shining in parts.
