A Mountain of a ProblemHardcover, 22 February 2022

Mystery-solving duo Shelby & Watts are back on the trail! They're saving the environment, one case at a time.

Violet the bear has awoken early from her hibernation, but she doesn't know why. She's called on Shelby & Watts to solve the case before her son, Theodore, is roused from his hibernation, too. With Shelby's deductive skills and Watts's scientific know-how, they'll leave no stone unturned or question unanswered.

In this follow-up to Tide Pool Troubles, our two environmental detectives uncover the larger issue underlying Violet's early start to spring: climate change. With accessible language and tips for what readers can do in the face of environmental change, this is a gentle introduction to one of today's most pressing issues.
