From the #1 New York Times best-selling author of Max comes a heartwarming, middle grade adventure story about a rescue dog, Star, who befriends a shy boy as they hunt for lost treasure near Lake Michigan.

When twelve-year-old Julian meets Star while volunteering at the shelter, Julian recognises the feeling of being an outsider but wanting to make friends. Julian's sure that Star is a diamond in the rough, just like him. He thinks they can prove that to everyone else by finding lost treasure near Lake Michigan. Will Julian and Star's friendship be the key to solving the mystery of Lake Michigan?
