My sister Isolde and I used to be human. The twin vampire princes, Caelum and Dorian, turned us and married us. The entire vampire world celebrated. Two human sisters, personally turned by the Crown Princes? It was the highest honor a mortal could receive. We believed we were loved. We were fools. Five months into my pregnancy, I was attacked by a group of exiled vampires in the forest beyond our territory. I called Caelum nine times. He didn’t pick up. The exiles circled me, cutting into my arms and legs with blades that burned. Pain tore through my body. I called a tenth time. This time, Caelum’s cold voice came through: “Haven’t you had enough? Vivienne is being tracked by hunters. Stop bothering me.” Vivienne was the human girl that both princes truly loved. The one who had refused to be turned. With nothing to stop them now, the exiles closed in. Their leader drove a blade into my stomach. I watched the light leave my body from the inside out, and felt my unborn child die. When I was close to death, my sister Isolde found me and fought the exiles off. But there were too many. Isolde was badly wounded. She called her husband Dorian for help. All she got was: “Looking for Vivienne. Don’t bother me.” Isolde carried me and ran. A storm hit and we were caught in the open at dawn—deadly for wounded vampires. The border patrol found us just in time. We barely survived. When I woke up in the infirmary, my first thought was simple: Sever the bond.

Vampires exist.  But they aren't the etheral,  seducing types that we are taught about.  They slither and scheme, kill and reduce to ash all that is around them and even worse,  One has claimed my heart as theirs.  Only, he doesn't know I'm not the woman he thinks I am.  I'm not his lover, nor do I want to be.  Kidnaped and forced into proximity with the King of the Dead I learn one thing, nothing is as it seems at first sight.  Hades is a man with power, but Thomas saved me from death.  One is human and the other is close to a God. A greater threat looms in the distance, the humans I wish to stand with are under attack. The Vampire's war is not mine to fight, but can I truly stay on the side lines and watch everyone I have come to care about perish?  And can I truly find love in the arms of a cold detached  man, when warmth and happiness lays in wait for me with Thomas?

I was born looking like the monsters my people feared. Pale skin. Silver hair. Features that made strangers recoil and my own family look at me with shame. In a world where humans and vampires have spent centuries locked in a fragile coexistence, resembling the enemy was enough to make me an outcast. So when our King demanded a bride for the Vampire Crown Prince to preserve the peace between our kingdoms, no one objected when I was chosen. I was never meant to return. Determined to despise the monsters who had stolen everything from me, I entered the Vampire Kingdom expecting bloodshed and cruelty. Instead, I found Mavros Moldark — the enigmatic prince, heir to a throne built on blood, whose silence concealed more secrets than the countless rumors surrounding his name. But the greatest danger wasn’t the prince. It was the kingdom itself. Behind gilded halls and royal smiles, every noble has an agenda. Every alliance comes with a price. Every whispered secret has the power to start a war. As I become entangled in the deadly struggle for the vampire throne, I begin to uncover truths that shatter everything I thought I knew about humans, vampires… and myself. Because peace was never the goal. I wasn’t sent to the Vampire Kingdom to become a bride. I was sent there to become a pawn. And I was the truth both kingdoms were willing to kill for.

My father had always been against my marriage to Ryan Kane, a vampire of noble birth. He believed that as a human, I had no place in the vampire world. He warned me that if Ryan ever changed his mind, without his protection, my half-blood child and I would be nothing more than walking blood bags in the eyes of vampires. But I believed in Ryan—and in our love. My husband had always been gentle and attentive. He had even defied everyone to make me, a human, his vampire bride. That was before Ryan's human ex-fiancée had her engagement called off and returned to the country seeking his help. I went to the hospital alone. While I was learning that my pregnancy was high-risk, Ryan was there attending her prenatal checkup, even introducing her to the doctor as his wife. All he had for me was one cold line: "Keep pushing me and I'll file for divorce." I pressed my hand against my stomach and dialed a number I hadn't called in years. "Dad, you were right... I want a divorce." Two weeks. That was all it would take for me to disappear from his life completely. But later—that same vampire who had discarded me like I was nothing showed up at my wedding to another man, trembling all over, calling my name in a broken voice.

My blood-bonded vampire mate left me while I was pregnant to be with his "first love" in the human world. When danger struck, he abandoned our son to protect her human child, who was not in any danger. While our son was struggling with lethal UV burns and calling for his father through a high fever, he was celebrating under citywide fireworks with that human boy, who only had a common cold. He even took the life-saving serum I had prepared for our son, just to use it for the boy’s "pre-transformation conditioning." He coldly stated, "Vampires are resilient; he’ll endure it. Human children are too fragile." After four years of raising our son alone, I finally decided to leave. I officially cut our blood ties and moved away with our son. Only then did he find out that his "first love" had been lying to him all along. After learning the truth, the arrogant vampire prince wept and begged for us to come back.
