After years of living on the Shore, Hannah Bell is sure of two things: 1. The family B&B is her future. 2. Men like Xander-mysterious, charming, and un-freaking-believably gorgeous-do not just wash up like some kind of sexy flotsam. But when Xander appears mostly-naked and half-conscious in the surf, Hannah does what any sane, kind-hearted woman would do: she hauls him into her bed. Her bed and breakfast, that is. It's only polite. But her one act of seaside charity goes sideways fast when her new perennially topless "guest" starts fixing leaky faucets with a wink, charming her with fishy dad jokes, and casually revealing that-oh yeah-he's a freakin' merman. Not only that, but he's the merman who rescued her a decade ago and then ghosted her like an enchanted Tinder date gone wrong. Rude. As Hannah reels from revelations and Xander tries to stay one step ahead of the secrets lurking beneath the tide, they'll need to figure out if their surfside chemistry is just a summer fling...or the start of something truly fin-tastic.
