Goodbye, Earl by Ava Devlin

Five years ago, Claire Hightower ran away from the man she loved.
Freddy Hightower had once been her reckless dream: a stolen groom, a whirlwind elopement, a future built on stars and scandal. But debts and dice chipped away at everything they had—until Claire fled with nothing but her unborn child and a fistful of pawnable jewels.

Now Freddy’s back.
Sober. Steadier. Still gorgeous and charming and chaotic—but also different. He’s returned to the Cotswolds for his mother’s wedding with an infuriatingly unflappable determination to win back his wife, his home, and his role as a father to the son he’s never met.

Claire isn’t handling it well.
She’s built a new life full of found family, sharp-tongued support, and exactly zero patience for handsome men with bread dough on their cuffs and cowlicks that match her son’s. But Freddy is relentless. Confident. Charming. And still so, so sexy. And he’s not alone: the meddling heroes and heroines of books past are gathered around her table, judging gently—and helping themselves to pie.
