When the vicious fae king catches Tessa stealing his powerful gemstones, he demands a cruel punishment. She must leave her family and friends behind and become his future human bride.

Tessa has never stepped foot inside the glittering fae city until now-no mortal is allowed. There, things are far more monstrous than she ever dreamed. King Oberon humiliates her, terrorizes her, and threatens those she loves.

But when she escapes, someone far worse finds her. The lethal Mist King, the enemy fae who trapped her people beneath the reign of King Oberon in the first place. The one who destroyed human cities and watched them burn.

He takes her captive and then offers her a deal.

Become the first mortal to kill a fae king, and he will free her people.

But the mists beyond the kingdom walls are dangerous, ruthless, and mesmerizing...and so is he. As Tessa fights her growing desire, she must make a choice.

Her dagger can kill only one fae. Which king will it be?
