Crunch by Leslie Connor. Age 10 and older. Dewey Marriss has a plan for the summer. He’ll manage his family’s bicycle repair business — because, after all, how can you enjoy summer if your bike isn’t working? But Dewey finds himself in a crunch (as in the title) when everyone needs a bike at the same time and he’s stuck watching his younger siblings. Can he keep all the wheels spinning and still have a great summer?
