A daring criminal is making waves in the Big Forest! It's up to Agent Moose and Owlfred to save the day in Operation Owl, the third hilarious graphic novel chapter book from Mo O'Hara, the author of My Big Fat Zombie Goldfish, with illustrations by Jess Bradley.

Agent Moose and not-quite-so-special Agent Owlfred are back and better than ever!

Strange flash floods are making waves (and headlines) all over the Big Forest! Someone is pulling off particularly confounding capers and, between the flooding and the heists, Big Forest is in big trouble. When Madame HQ is nabbed right out of a very wet Woodland HQ, Agent Moose and Owlfred must wade through clues to get her back and stop the mystery criminal making a big splash in Big Forest!

Can they find this fiendish villain before Big Forest floats away?
