Penelope Ramos has dreamed of being a K-9 search-and-rescue handler since she was a little girl. Armed with a quick mind and her German shepherd, Havoc, she rides into Maple Falls, Vermont, determined to get her certification. She isn't expecting the gruff, unreadable park ranger assigned to evaluate her skills.

Park ranger Jay Gosling is a pro. It's clear to him that neither Penelope nor her unpredictable canine has what it takes...although his boss feels otherwise. Whatever. Jay will never have to work with them and he has half a mind to escort them both right out of town. But when a young boy goes missing, he doesn't have that luxury.

Working side by side tests their tentative peace, but Jay and Penelope are together on one thing: they'll both do whatever it takes to find the missing child--before it's too late.
