September Sneakers

On the final morning of summer vacation in the small town of Green Lawn, four young friends face an unexpected school-year mystery. Twins Bradley and Brian Pinto, along with Nate Hathaway and Lucy Armstrong, have spent their holidays caring for Goldi, the first-grade class's pet hamster. But when they prepare to return her to school, they find Goldi's cage empty, replaced by a tiny green-and-orange sneaker keychain. Soon, full-sized sneakers begin hanging from trees all over town, and other strange objects start vanishing. As Book #9 in the Calendar Mysteries series, this early chapter book follows the kids as they track down clues, hunt for the elusive sneaker sneak, and attempt to bring their class pet home safely.
