When Killian Quinn, captain of offshore fishing boat, receives a distress call from a sailing ship caught in a terrible storm, he and his crew rush to provide aid. But when they arrive, all that's left of the ship and its crew is splintered wood and a borderline hypothermic woman who can't remember how she survived. His attraction to her is instantaneous, and maintaining a professional distance proves to be a struggle, especially when she needs a place to stay that's far from the press and curious townsfolk, and his idyllic cottage by the sea is the perfect sanctuary.
What was supposed to be a thrilling once-in-a lifetime opportunity for Lorelei Roth, turns into a seafaring tragedy. As Lorelei struggles to accept that she's The Osprey's only survivor, she's plagued by strange dreams and sleepwalking episodes that draw her into the ocean. And if the grieving process wasn't hard enough, Lorelei also grapples with guilt from developing feelings for the captain who rescued her. But worst of all, is a new, unsettling hunger for raw flesh that's eating her from the inside out. The handsome captain begins to look like a tasty snack in more ways than one.
Discovering she's descended from the people-eating mermaids who devoured her crew, Lorelei struggles to accept her identity knowing her entire existence relies upon its secrecy and devouring human flesh. What happens if Killian finds out? The world at large? What if Lorelei answers the ocean's call to the deep?
