From USA Today bestselling author Claudia Burgoa comes a new best friend's sister, forbidden romance filled with humor and angsty at times. It all started on a dating app and a fake name. Instead of a hot hook-up, I end up face-to-face with Kingston St. James. He's one of the most striking and wealthy men in Seattle-as well as my brother's best friend. Logic dictates I walk away, but curiosity wins and we follow Myka's Easy Rules for Healthy Hookups: Rule #1: Don't expect anything. Rule #2: Never wish for more. Rule #3: Don't swoon. Rule #4: Don't give endearing nicknames to your hookup. Rule #5: Don't be possessive, your hookup doesn't belong to you. Confession time: I'm making up the rules as we go. And surprise, surprise, this casual fling rapidly evolves into a friend-with-pretty-weird-benefits (and not the sexy kind). Kingston is suddenly breaking the hookup rules. He's all charm and affection, turning possessive and... probably hoping for more than just a fling. We accidentally find ourselves tangled in something more than just a fling. It's something dangerously close to love. We might be heading into a collision where the most beautiful accident or the most disastrous end might happen.
