The Bully by Willa Nash

Nellie Rivera is trading traffic for tranquility. When the quiet streets of small-town Montana beckon, she leaves Denver behind and moves to Calamity. It would be the perfect adventure if not for Cal Stark.
When her archnemesis dares to show his face one Saturday morning, declaring he is moving there too, she vows to make his life a misery. The town isn’t big enough for the both of them and besides . . .
She was here first.
Cal has been a thorn in her side since high school. He might have bullied her back then, but she’s not a modest teenager anymore and has learned a few plays of her own. If all goes to plan, she’ll run the former pro quarterback out of town within a month.
There’s only one problem. Cal has the same plan. He wants Calamity bad enough to pull out all the stops. And after one kiss, she realizes that he doesn’t play fair.
