This is the story of an eight-year-old girl who does her best thinking upside down. Her personality is a tractor beam, her attitude is completely inspiring, and her creator is a creative dynamo.

Beatrice is looking forward to a year of pirate adventures, zombie battles and upside-down mysteries with her fellow-tomboy best friend, Lenny. But on the first day of year three, Lenny doesn't come to school in a ninja suit like they'd planned - instead she's wearing something pink and sparkly and ruffled. She doesn't seem interested in their old games any more, and worst of all she's found a new friend. It will take Beatrice's best upside-down thinking to find a way to fix this problem.
