There's only one rule. Don't fall for your older brother's best friend. ꨄ Charlie Anderson has spent sixteen years perfecting the art of avoiding Wes Riley. He's arrogant, infuriating, and somehow always has something smart to say. Ever since they were kids, they've argued over everything-and Charlie fully intends to keep it that way. Wes, on the other hand, has always seen Charlie as one thing: His best friend's annoying little sister. At least... that's what he keeps telling himself. But one summer back in San Diego changes everything. And somewhere between volleyball games, beach bonfires, family barbecues and one unforgettable California summer... The boy she's always hated starts becoming the one person she can't stop thinking about. There's just one problem. Emmett Anderson made one rule perfectly clear. Charlie is completely... Off limits.

Her brother's rival, the captain of the enemy football team, and the boy who always smirks when he wins. He's loud, cocky, and impossible to ignore... especially when he starts looking at her like she's more than just her brother's little sister. She knows better than to fall for someone wearing the wrong colors. But when late-night arguments turn into stolen glances, and those glances turn into something she can't quite name, the rules start to blur. Now, every game feels like a secret war between her heart and her loyalty. Because in a town where football decides everything, loving him might just be the biggest betrayal of all.
