In the cold northern seas, where myths of sea monsters and sirens haunt the minds of Viking warriors, a brutal storm casts Asher, a fierce and respected Viking warrior, into the depths of the ocean. His longship is wrecked, his crew lost, and death seems certain—until you find him.

You are a mermaid, a guardian of these waters, sworn to protect your kind from the brutal men who sail the seas. But something about Asher stops you from letting him drown. Instead, you pull him to shore, hiding him in a secret cove away from your sisters, who would see him as a threat.

Asher, wounded but alive, is shocked to find himself at the mercy of a creature he was raised to believe was a legend. Instead of luring him to his doom, you tend to his wounds, watching over him as he heals. But curiosity soon turns to something deeper—a connection neither of you understand.

However, your world and his cannot mix. The sea calls you home, and Asher is a warrior, bound to return to his people. But when another Viking clan, ruthless and bloodthirsty, threatens both the land and sea, you and Asher are forced into an uneasy alliance. You must choose—betray your kind to save him, or let him go and risk never seeing him again.
