A Mountain of a Problem: Shelby and Watts, Book 2, by Ashlyn Anstee (Ex-Library HC)

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.
