In a world where animals are slowly fading into extinction, twelve-year-old Kester Jaynes feels as if he hardly exists either. He’s been locked away in a home for troubled children and is unable to speak a word. Then one night, a flock of talking pigeons and a bossy cockroach come to help him escape, and he discovers that he can speak—to them. And the animals need him. Only Kester, with the aid of a stubborn, curious girl named Polly, can help them survive.
