The Screwup by Alina Jacobs

He brought a fake fiancée to family dinner and she’s stirring up trouble.
Carter Holbrook—bad boy, heir to billions, and the family screw up. He can’t help but cause trouble wherever he goes, be it at a family gathering…or at Allie Larson’s bar.
Proud of her work ethic and self-reliance, Allie will do (almost) anything for money, and she readily agrees when Carter asks her to be his fake fiancée.
For his latest and greatest instigation, Carter wants to bring this sassy bartender home for dinner at his family’s posh New England estate.
Keeping business and pleasure separate is how she’s survived on her own all these years, and to endure the long weekend as Carter’s fake fiancée, Allie concentrates on the facts.
One: His family is horrified to learn she’s Carter’s (fake) fiancée.
Two: It doesn’t matter how trashy she acts because she will, thankfully, never see Carter or his family ever again.
Three: Carter actually kisses her.
Wait…what?
Allie knows she’s not the type of girl who really marries a guy like Carter. She knows the weekend at the Holbrook estate was just for laughs. But when fate serves up a special drink of its own and pushes Allie and Carter together, can Allie let herself be loved?
