King of the Sea by Elizabeth Frost

A half breed called by the sea.
A faerie king who desires adventure.
A churning ocean needing a hero.

River hasn’t always fit in. Actually, she’s never fit in with the small town where she lives with her father. Isolated and lonely, she finds solace by the sea where she draws. Until a strange man comes out of the waves and promises her an adventure.
She’s not stupid. He’s a stranger, and he could be some psycho killer. Except there’s something captivating about him.
One adventure. One deal. Just a few moments where he reveals a hundred hidden secrets she’d never known about herself. And the more she spends time with him, the more she wants to learn.

But something dark lurks in the depths of his soul. Something which threatens both of them.
