Once upon a time, an unruly puppy was looking for a place to call home...

Connor Wyeth has a plan for everything. But when he adopts Maximus, an unruly Irish wolfhound mix, he gets more than he bargained for. The only person Max ever listens to is the volunteer who used to walk him at the shelter - a perpetually upbeat woman whose day job is planning princess parties for little kids. Connor can't believe she'll be able to tame such a beast as Max, but he's desperate enough to try anything.

Deenie Mitchell isn't looking forward to spending more time with uptight, rules-orientated Connor - no matter how attractive he is. But when her sister announces her engagement, Deenie realizes he's the perfect person to impress her type-A family. When she learns he needs a plus-one for his law firm's work events, an unlikely alliance is formed. But then playing the perfect couple unexpectedly begins to feel all too...real.

Opposites may attract, but can this rule-maker and rule-breaker find a way to each other's hearts?
