Silver Hawk's Revenge (Light Traveler Adventure Series, Book 2)

In the first book of this series, we meet Bart Elderberry, a young man with the amazing ability to leave his body and go floating around as a spirit. He solves a mystery and the bad guys end up in jail. But in this book, they get out of jail, and Bart discovers they have a secret weapon on their side -- a man who can also leave his body, but he is evil. With good friends at his side, Bart goes on a quest to conquer this new challenge and save . . . well, we won't give everything away. We'll just say, as much as I loved the first book, this one is even better.
