The Golden Rectangle

Gr 4–6—Ten-year-old cowgirl Lucy Moon couldn't be more different from fashionista Flor Bernoulli, the superstar introduced in The Secret Spiral (S & S, 2011), yet they are destined to work together to save the world from Square Man and his evil plan to destroy all curves and things round. Together with Dr. Pi, a friendly baker and wizard, and Lucy's dad, they fly through time and space to achieve their goal. Riddled with math terms and plays on words, the text can be humorous and clever, although perhaps lost on general readers. Even the title is part of a mathematical theorem. There is also a situation in the beginning of the novel that doesn't contribute to the story line and is never revisited. Recommend this book to true fantasy or math lovers; possibly it could be used as a supplemental introduction to trigonometry.—D. Maria LaRocco, Cuyahoga Public Library, Strongsville, OH
