Twin siblings Sara and Paul discover a giant mouse named Millie in the fridge in French's debut picture book. Sara and Paul are bored with all their favorite games when Sara decides to get a drink. When she returns with a glass of juice, Sara announces that there's a mouse "as big as a cat" in the fridge. A skeptical Paul investigates and discovers that the remarkable mouse is not only larger than average but is also able to talk. The indignant mouse introduces herself as "a girl named Millie," adding "Of course I talk! I'm a talking pro! I'm not an ordinary mouse, you know." Soon, Millie ropes the twins into helping her bake a chicken potpie, using all the available ingredients in the house. These include rice, bananas, peas, a bag of potato chips, chocolate sauce, jam, ham, vinegar, "a nice fat prawn" and vanilla ice cream—but no chicken. The twins question Millie about the missing ingredient, but Millie shrugs off their concerns and confidently plows on. She stirs the strange concoction wildly, leading to a fun, surprise ending. French's charming tale has an exuberance and wit that should delight any child. The big, brassy, enthusiastic personality of Millie will jump off the page; some readers will take to Millie as a much beloved partner in crime when she urges the twins not to tell their mother about dinner since "she'll spoil the fun." French's simple but enchanting and expressive illustrations display the mischievous Millie in a variety of moods and poses. Lively and active, the drawings depict the entire story for children who can't read, culminating in a humorous climax. A delightful children's tale with an engaging, larger-than-life lead character.
