The Ever King by LJ Andrews

The first in the series that took the world by storm, The Ever King is full to the brim with magic, pirates, fae and sizzling romance . . .

They stole his crown, so he stole their daughter...

For years Erik, the scarred king of the Ever Kingdom, has thought of nothing but vengeance against the man who killed his father and trapped him beneath the waves, making him a prisoner in his own realm.

Until his enemy's daughter unintentionally breaks the chains on the Ever, and Erik makes her the unwitting pawn in his vicious game of revenge.

She's innocent. He's vicious. But he will take back what he lost, no matter the price.

Unless she steals his heart first.
