Query: Haunting, whimsical, wonderful

This is the first online book review I've ever been moved to write.The story is sophisticated (few kids' books I know of dare first-person narration; fewer still go beyond a neatly-put-to-bed ending), yet it is both accessible to a young audience, and engaging for the adults.The Lost Thing is cinematographic in its detailed, industrial-style illustations. The matter-of-fact storytelling about an extraordinary experience somehow add to the magic.This is one of the books my kids will examine for ages, "reading" long before they can really read.Wonderful.
