When a horse stable opens near Maddy's house, Maddy sets her sights on horseback riding lessons. But lessons are expensive, so she comes up with a brilliant plan to earn the money to pay for them: Pet Camp! Maddy will host a summer camp for one week. The twist? Each camper gets to bring their pet. Unfortunately, the practical details turn out to be trickier than Maddy imagined. The rabbit gets lost, the dog eats all the snacks, and Maddy's brother and his best friend won't cooperate. And what is this "mystery pet" one camper keeps talking about? Will Maddy manage to get things back under control, or will her camp flop embarrassingly? Aligned to Common Core standards and correlated to state standards.
