The Mist Thief by LJ Andrews

She tried to kill him, so he made her his wife. From million copy bestseller L. J. Andrews, The Mist Thief returns to the world of The Ever Seas, bursting with pirates, fae and sizzling romance.

Skadi first met her husband-to-be with blades in hand on the opposite side of a battle. She lost, and he claimed his prize.

To her horror, the king of the shadow elven agrees to marry her off to Jonas, a prince in the fae realms, as a way to unite their kingdoms against a shared enemy-the light elves. Skadi knows the marriage is nothing but a political game. Feelings won't come into play.

Except her new husband makes not falling in love... challenging.

When new threats arise, Skadi must decide either to love her enemy or keep him alive by betraying him to another.
