Crossbones

"Sarah and Ryan are in deep trouble...they've discovered a dark secret ... something that everyone in their hometown of Skeleton Creek, Oregon, seems to want to keep from them. Why? It just doesn't make sense. The answers are at the old, abandoned dredge. The last time the two teenage detectives went out to the creepy dredge, Ryan ended up unconscious and in a cast at the hospital. Ryan is stuck at home, but Sarah can continue to solve the mystery by taking videos. Forbidden to speak with or contact Sarah anymore, they communicate through text messages, midnight meetings and Sarah's videos posted on her secret website using passwords given throughout the book."--Provided by publisher.
