The Woods by Harlan Coben
Paul Copeland, a prosecutor, lost his sister years ago when she disappeared into the woods. Now, while working on a major court case, evidence surfaces when a murdered man who was last seen with his sister is identified. He was suspected of having died with his sister. Challenged from multiple issues, Copeland battles to solve the mystery that has haunted him since his teens.
Coben is another new author for me. I will not hesitate to grab another of his in the future. Lots of twists and turns in this suspenseful story.
