The protagonist in Harlan Coben’s latest action-packed thriller, The Boy from the Woods, was, as a boy, found living in the woods without memory of his past. He grew up to become a private investigator. The main plot involves bullying teenagers, kidnapping, and tapes incriminating a rising politician with dictatorship tendencies. It’s a fast read and there’s lots of action. A small complaint I have is there are too many subplots and improbable coincidences. Here’s what Kirkus Reviews says:
