There's No Such Thing as a Snappenpoop

Jeanne Willis turns a nonsense word into a genuinely satisfying story arc — the bossy older sibling's scheme backfires through sheer imaginative force, which is exactly the revenge fantasy younger siblings deserve. The premise is tight, the resolution earns its magic, and Willis's experience as a storyteller means there is no wasted page here. The 'poop' in the creature name will either delight or mildly irritate parents, but children will absolutely love saying it.
