She does everything right. So what could go wrong? Mackenzie 'Mac' Cabot is a people pleaser. It's exhausting, really, always following the rules. Mac has dreams of her own but to please her parents she moves to the beachside town of Avalon Bay to get her college degree. Twenty-year-old Mac has had plenty of practice suppressing her wilder impulses, but when she meets local bad boy Cooper Hartley, that ability is suddenly tested. Cooper is rough around the edges. Raw. Candid. A threat to her ordered existence. Their friendship soon becomes the realest thing in her life. Despite his disdain for the trust-fund kids he sees coming and going from his town, Cooper soon realizes Mac isn't just another rich clone and falls for her. Hard. But as Mac finally starts feeling accepted by Cooper and his friends, the secret he's been keeping from her threatens the only place she's ever felt at home.
