The story

When Dink, Josh, and Ruth Rose visit a friend's castle on the Maine coast, mysterious screams echo through the walls. Their investigation leads them through hidden tunnels, rising tides, and a wildlife crime that turns out to be far more serious than a ghost story. Along the way, they learn that the most trustworthy-seeming people aren't always what they appear.

Age verdict

Best for ages 7-9. The mystery is engaging without being scary, the vocabulary is accessible, and the 96-page length feels achievable. Younger kids enjoy it as a read-aloud; older kids may find it too simple but still entertaining.

Our take

Solid classroom mystery with strong gateway and reluctant-reader appeal. Teacher scorecard leads due to cross-curricular connections and accessible format. Parent scorecard is modest — the book entertains and teaches but doesn't deeply challenge emotionally or intellectually.
