Thrilled to find a long-abandoned bus, Morgan, Amy, Carlie, and Emily begin to clean it out to use as a clubhouse. As they work on the bus, they discover clues that suggest someone who lived in the bus in the late 70's. They find a box of dusty treasures, including a 25-year-old high school yearbook. Whoever lived there had a mysterious past and is somehow connected to the grumpy park manager, Mr. Greeley. An old journal could hold the key, but are all stories meant to be told? Recommended for ages 8 to 12.
