The new guard

"Booker the bat has completed his training and he's excited to report for duty as the newest guard at the Joanina Library in Coimbra, Portugal. His job is to fly through the stacks at night, gobbling down the bugs that are in turn eating the 200,000 antique leather books. It's the perfect job for Booker, because he loves to read. And now he's saving books! . . . When Booker spots a human attempting to steal pages from one of the valuable books, he summons his courage, (echo)locates the other bat guards, and swoops in with a plan to save the day!"--Provided by publisher.
