Cecily Hampton's first date with Dominic Bellinger started out like a dream. The conversation? Flowing. The chemistry? Sizzling. But when Cecily overhears a phone call Dom steps away to take, she grabs her purse and makes a run for it. She knows a red flag when she sees one.

Unfortunately, avoiding Dom becomes impossible when they're both summoned to Las Vegas to celebrate their mutual friends. Armed with a vow to hate Dom forever, Cecily lands in Sin City ready to unleash her dirtiest looks on him. Except, Dom's salty attitude is making it clear Cecily isn't the only one with hard feelings.

When shooting daggers turns into shooting tequila, Dom and Cecily wake up to find themselves with a nasty hangover and new titles: Mr. & Mrs.

A rush to undo the drunken mistake is halted when Cecily's grandmother calls to announce she's dying, and her final wish is to road trip around Arizona with her family. Including her granddaughter's new husband.

Cecily can't decide which is worse - being stuck in a luxury motor coach with Dom, or her estranged family.

But somewhere between a stay at a haunted hotel and unwittingly attending a nudist colony, their thinly veiled insults and barbed remarks give way to the attraction from their first date. They tell themselves it's just this once...twice...ok, three times.

Scratching an itch starts looking a lot like newlywed bliss. And their temporary marriage? It just might turn into forever.
