The Pet Library: Something Fishy

Audrey Plum has her heart set on borrowing a turtle from the Pet Library. But when baby sister Cora ruins her plans, Audrey must settle on a different pet... (drumroll...yawn). A fish. Are fish really the most BO-RING pet, as everyone says? Maybe not. But there is nothing boring about the Pet Library's newest addition-Agatha. Will she become the next target of mean boy Desmond Crane and his awful practical jokes?
