SPF at the ready… someone's about to get burned.
As a year-round resident of Cape May, New Jersey, Maisie Mundy has grown up loathing the "shoobies" that flood her charming seaside town each summer and treat it like their personal playground. And when it comes to shoobies, there's none worse than Preston St. James, the arrogant heir to the St. James Development Company, the same company that's trying to drive Maisie's grandfather's beach umbrella company out of town to greenlight their latest downtown project. Maisie is the only person aware of the dire financial situation her grandfather has found himself in, and she's the only person who can save the shop, peddling rental umbrellas on the beach daily, doing whatever it takes to keep Mundy's Sundries afloat. When Preston launches a beach delivery app to win a Shark Tank competition at his private school, he gives Maisie a whole new reason to hate him. Immediately, the two become engaged in a battle of rumor-spreading and sabotage that could sink them both.

But as Maisie's best friend Summer points out, hating someone that much takes a lot of passion, and the more time Maisie spends duking it out with Preston, the more that passion starts looking like something else entirely; the more it starts looking like romance. The closer Maisie and Preston become, the more she trusts him with her heart… and her family's secrets. Is Maisie a fool for trusting a St. James, or will her lack of faith in Preston be the real reason she gets burned this summer?
