PreS-K— A child bids farewell to his parents (who are sent back to their own planets) and begins his first mission on Planet Kindergarten. He is joined by intergalactic aliens, all reporting to a commander whose desk is littered with apples. The gravitational field is different: "We have to try hard to stay in our seats. And our hands go up a lot." Projects include exploration outside the capsule, keeping logs, and, most challenging of all, extended rest time. "Abort mission," the homesick space traveler thinks. Then he remembers what's said at NASA: "Failure is not an option." Before he knows it, he's in splashdown—back home— and training for his next mission. Ganz-Schmitt exhibits a fine mix of sensitivity and pizzazz in approaching the challenges that children face. With the help of Prigmore's superpowered animation-style illustrations, she offers a story that will help readers understand that kindergarten really is out of this world.—Susan Weitz, formerly at Spencer-Van Etten School District, Spencer, NY
