Wounded (The Wereling #1) by Stephen Cole

While on a family vacation, 16-year-old Tom Anderson has a terrifying run-in with a bear that sends him hurtling down rapids in a river, barely escaping with his life. When he wakes up, he discovers that he is being cared for by Marcie, a nurse who lives in the remote woods. Soon the teen starts to sense that something strange is going on. Not only is he feeling weird (heightened senses and a strange craving for raw meat), but also Marcie's daughter, Kate, seems to be trying to tell him something. And then one night he learns the shocking truth: the Folans are werewolves, and they have been trying to turn him into a mate for Kate. After a violent scene that leaves Kate's little brother dead, Tom and Kate flee for their lives. They must reach a witch doctor in New Orleans who can turn him back to human, but they must hurry, because the countrywide network of werewolves is hot on their trail.

This book is great! It took me a little bit to get into the story, but once I did I was hooked. There is lots of action and adventure, plus the constant feeling that Kate's mother Marcie is right behind them ready to exact her revenge. This series will be great for teens who enjoy supernatural elements or horror stories.
