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.
