Connor Wyeth has a plan for everything. But when he adopts Maximus, an unruly Irish wolfhound mix, he gets more than he bargained for. If he doesn’t act fast, the big dopey mutt is going to destroy his house. The only person Max ever listens to is the volunteer who used to walk him at the shelter—a perennially upbeat woman whose day job is planning princess parties for little kids. Connor couldn’t ever imagine that she’d be able to tame such a beast as Max, but he’s desperate enough to try anything.

But as they play the perfect couple, the friendship—and the feelings—that are forming start to feel all too real.
