Heidi Heckelbeck and the Lost Library Book (Heidi Heckelbeck, Bk. 32)

The Brewster Library has always been a magical place for kids in town. It has a story waiting for everyone. But imagine Heidi's surprise when Aunt Trudy lets her in on a well-kept secret: The Brewster Library has a magic section! When Heidi checks out a book that floats down from the shelf to her, she learns that you can't always judge a book by its cover. Especially when it's a bewitched book that loves to play pranks.
