On her 30th birthday, Elle flees to Vegas for a blind date with her best friend Kennedy's famous musician brother Pierce—only to accidentally marry a wealthy stranger named Mr. C. Back home, as Elle tries to piece together the wild night, she moves into the Chamberlain Estate guesthouse, and almost instantly runs into: Oliver, Pierce Chamberlain's manager - and clearly disliked by Kennedy. Elle realizes: this is the man she married in Vegas last night! As these two opposing personalities navigate how to live with one another, more secrets unravel, namely that Oliver isn't JUST the manager of Pierce Chamberlain...he's the OTHER Chamberlain brother, aka Kennedy's brother too. He has harbored a crush on Elle for months after meeting her at a photoshoot. When he married her in Vegas, he had no idea she was so close with his little sister and that to keep the truth from coming out, he'd have to create a house of cards, that ultimately falls around him. What starts as a drunken mistake turns into a slow-burn, high-stakes love story—full of mistaken identities, glamorous family drama, and laugh-out-loud misunderstandings—culminating in Elle discovering the truth finding real love and finally getting true partnership in her unexpected husband.
