Tessa Blake likes things simple: clean layouts, crisp deadlines, and a boyfriend who's been her best friend since college. What she doesn't like? Camden Price-her boyfriend Noah's childhood best friend and living proof that loud, obnoxious energy drinks can take human form. So when Cam crashes their quiet weekend plans with a smug grin and a new girlfriend, Tessa prepares for another evening of pretending to tolerate him. She definitely doesn't expect Harper Rhodes. Harper is calm, self-assured, and infuriatingly observant. An independent photographer with a quiet voice and a sharper lens, she notices things most people miss-including the cracks in Tessa's carefully arranged life. What begins as forced double dates turns into long conversations, unexpected laughter, and a slow unraveling of everything Tessa thought she wanted. As her long-term relationship starts to feel less certain and Harper becomes harder to ignore, Tessa is forced to ask herself: What if the person she can't stand leads her to the person she can't live without? Sometimes your "plus one" is the one.
