Adult Reader Reaction: The story is funny, but also poignant. Zengo is an "every platypus" character - clever, unsure of himself, and prone to jump to conclusions. The mystery is well presented. There is just enough suspense to keep you reading, but neither scary nor predictable. I highly recommend this as a read-aloud.

Pros: Humor, down-to-earth characters, and good ol' detective work combine in a great story for upper elementary and middle school readers.
