The Prince by Jennifer L. Armentrout

She’s everything he wants….
Cold. Heartless. Deadly. Whispers of his name alone bring fear to fae and mortals alike. The Prince. There is nothing in the mortal world more dangerous than him. Haunted by a past he couldn’t control, all Caden desires is revenge against those who’d wronged him, trapping him in never-ending nightmare. And there is one person he knows can help him.

She’s everything he can’t have…
Raised within the Order, Brighton Jussier knows just how dangerous the Prince is, reformed or not. She’d seen firsthand what atrocities he could be capable of. The last thing she wants to do is help him, but he leaves her little choice. Forced to work alongside him, she begins to see the man under the bitter ice. Yearning for him feels like the definition of insanity, but there’s no denying the heat in his touch and the wicked promise is his stare.

She’s everything he’ll take….
But there’s someone out there who wants to return the Prince to his former self. A walking, breathing nightmare that is hell bent on destroying the world and everyone close to him. The last thing either of them needs is a distraction, but with the attraction growing between them each now, the one thing he wants more than anything may be the one thing that will be his undoing.
She’s everything he’d die for….
