A heartwarming Christmas mystery and friendship story! Every Christmas in the small town of Pine River, a tree appears in the town square--the Angel Tree. Some people tie wishes to the tree, while others make those wishes come true. Nobody's ever known where the tree comes from, but the mystery has always been part of the tradition's charm. This year, however, four kids who have been helped--Lucy, Joe, Max, and Cami--are determined to solve the mystery and find out the true identity of the town's guardian angel, so that Pine River can finally thank the person who brought the Angel Tree to their town. This is a heartwarming Christmas mystery, full of friendship, discovery, and loads of holiday cheer!
