By Avi, Author & Brian Floca, Illustrator. From Newbery Medalist Avi comes a deliciously funny animal fantasy set in 1900 Central Park, where animals—and baseball—rule supreme. Life is good for Oscar Westerwit. He’s the mayor of Central Park. He’s also the shortstop and manager of his baseball team. What could be bad? Plenty, that’s what! Big Daddy Duds, jewel thief, thug, and leader of the rats, is about to invade the park, and Oscar must stop him before the rats take over. For ages 8 and up.
