Break Me Like a Promise by Rebecca Stone

Ruby Delacey is living the dream in New York City. Then her mom gets sick, forcing Ruby to return to Oak Valley and face her ex-boyfriend.
Her now-rich, kind-of-an-asshole, still-devastatingly-hot ex-boyfriend.
Football was Colton Taylor’s ticket out of Oak Valley — and away from his memories of Ruby Delacey.
Then a knee injury sends him home with wounded pride and a ton of money and Colton pivots to the long-dead dream of opening his own pastry shop. It’s all lease agreements and commercial ovens — until he discovers Ruby’s back home too.
No problem. He’s been fine without Ruby Delacey for ten years. He’ll just avoid her until she (inevitably) bails on Oak Valley again.
But when Ruby’s plan to convert a school bus into a home on wheels requires some hands-on muscle, Colton finds himself right back where he swore he’d never be again — standing at her side, this time with a hammer and a heart full of shiny new dreams he tries ignore.
Now Ruby can’t help wondering if her happily ever after is closer to home than she thought — and if the man she once abandoned can ever trust her enough to give her second chance.
