Oliver Olson’s problem could easily be every kid’s dream: His parents do his homework for him. But they are also so overprotective that the 3rd-grade space sleepover is absolutely out of the question for Oliver. When he connects with outspoken classmate Crystal about their mutual dismay at Pluto’s demotion from planet-status, Oliver begins to feel more confident about expressing his opinions, even as he fears disappointing his parents. Heartfelt and emotionally resonant, but full of humor and deftly drawn characters, Mills has created another winner for young readers. Grades 2–4.
