Adventure, imagination and loads of fun. From the bestselling author of Alice-Miranda comes this humorous and heartfelt series about eight-year-old Willa and her best four-legged friend, Woof! Willa's in trouble. Mimi - the famous racing pigeon owned by Frank, her neighbour and best old-aged friend - is missing. And Willa is pretty sure she's the one who left the cage door open . . . She'll need her most creative ideas (along with the help of Tae, her best same-age friend, and her trusty sidekick Woof, the albino Irish Wolfhound) to track Mimi down before Frank finds out! Can Willa find Mimi before it's too late?
