"Gr 5-8-Tweens will learn more about a likely fascinating subject--themselves! In one lazy afternoon, young people can evaluate their memory, discover their Myers-Briggs personality type, and find out just how well they know their closest friends. Plenty of fact and theory go along with the pencil exercises, memory challenges, and games to play with groups. Readers will pick up vocabulary like telekinesis and clairvoyance and learn about thinkers like Sigmund Freud and Carl Jung. Cool black-and-white brush and ink doodles give the design an edgy feel, and stock photos show a diverse cast of children and families, often in outdoor settings. Personality, Memory, and Left Brain, Right Brain contain the most entertaining activities, while Astrological Signs is perhaps the weakest of the bunch, with quizzes that seem to yield arbitrary results. VERDICT This series is going to be very popular in middle school libraries."--School Library Journal, Series Made Simple.
