While this is obviously inspired by Scooby Doo, it's very much an adult book. It quickly moves from the expected/traditional whodunit to a more supernatural story, but does continue as a mystery throughout the book. The ending was a little less than satisfying - an extra scene tacked on after the mystery is "solved" that didn't really add anything of substance in my opinion. Overall it was an enjoyable read, there are a couple heavy-handed references to Scooby Doo like a river being names "Zoinx/Zoinks" but it can be a fun read for those that aren't Scooby fans.
