For the last decade, King Lazuli of the Eastern Empire has systematically taken over the world. No one knows much about him other than a series of impossible facts: he cannot die, he has not aged since the conflict began, and he wants to rule the world. All Serenity Freeman has known is bloodshed. War has taken away her mother, her home, her safety. As the future emissary of the Western United Nations, the last autonomous region of the globe, she is responsible for forging alliances where she can. Surrender is on the horizon. The king can taste it; Serenity feels it deep within her bones. There is no other option. Now the two must come face to face. For Serenity, that means confronting the man who’s taken everything from her. For the king, it means meeting the one woman he can’t conquer. But when they meet, something happens. Cruelty finds redemption. Only in war, everything comes with a price. Especially love. less

They say I am a queen. They say I married a monster. That I did so willingly. They say he cannot die, that he does not age. That together, we rule a ravaged world. They say I used to be one of them, but now I am a traitor. They say many things, all which I cannot remember, but …. I fear what they say is true. Then there is what they don’t say, what I see in their eyes—. The king terrifies them. He cannot be stopped. And, most worrisome of all …. He is coming for me.

She’s a martyr. A myth. A ghost. A legend. She’s my soulmate and my captive, my conscience and my wrath. I love her too much to let her die; I fear her too much to wake her from her slumber. She’s mine. And now she’s gone. He’s unnatural. Undying. Unethical. Unstoppable. He’s the keeper of lies and lost souls. Mine slipped through his clutches. I am his wife, his queen, the love of his very long life. And soon, I will be his executioner.
