Frognapped

In the third book of the Araminta Spookie series, Barry Wizzard's frogs are stolen and Araminta and Wanda must find them. If you're looking for chapter books for kids ages 6-10, this series from Angie Sage, author of the New York Times bestselling Septimus Heap series, is a great choice.
Usually Araminta gets blamed when something's amiss in Spookie House. But this time she had nothing to do with the disappearance of Barry Wizzard's frogs, and she is determined to find them. It's not going to be that easy, especially when dealing with a crazy character named Old Morris, a dangerous shark, and a demanding aquarium show audience. Can Araminta find the frogs and steal the show?
