Dark Redemption by L.A. McGinnis

They say kingdoms rise and kingdoms fall…
But I’ve seen the future.
And this time, none of us survive what’s coming.
After a hard fought, bloody battle, the Vampire High Council lies in ruins. While some say we’ve won the war, a new enemy has emerged from the shadows, impossibly ruthless, dangerously bloodthirsty, too powerful to defeat. Acheron was the first vampire Caine made, and he’s set his sights on me.
He plans to make me his bride. His weapon. His pawn.
He’s the predator and I’m the prey—but I have a secret—six of them, actually.
A king who will die for me. A warrior who will fight for me. An assassin who will kill for me.
And three powerful Elders who now owe me their lives.
Though our cat and mouse game has just begun, I refuse to hand our world over to a monster without a fight. But when Nikolai offers me an impossible choice, will I spend one sizzling night with him to save the males I love? Or face a foe I cannot hope to defeat and die alone, protecting my kingdom?
