Midnight Hunger by K. Loraine

Lucas Blackthorne ruined me.
Because of him I lost my pack. My heart. My soul.
He was the bastard prince of the Blackthorne vampires, and I fell for his charms. It’s a mistake I won’t make again. He’s wicked and dangerous, but I have plans for revenge.
Lucas might be estranged from the royal family, but that doesn’t mean he’s not useful. I’ll turn him against his brother and bring down the vampires once and for all. Just like he tried to do with me, once upon a time.
He stole my heart once before.
He can’t take it again.
But it’ll be fun to let him try.
