Anthropologist Eva Ling lives for dissecting garbage—until digging through her neighbor's trash leads to a bloody discovery: Vincent Grant, a reclusive man whose diet consists solely of blood sausages and whose eyes glow crimson. After he mistakes her for a call girl and forces a kiss, Eva's life spirals into darkness when a ruby ring she salvages from the trash gets her kidnapped to Crimson Crescent Isle—a Greek sanctuary for vampires. Vincent, the clan's brooding leader, gives her an ultimatum: become his immortal bride or die. Trapped on the island, Eva is hunted by blood-crazed vampires like the elegant rival Nadine Frost and the unstable butler Mr. Finch. Yet amid the terror, she glimpses Vincent's tormented soul and feels an unexpected pull toward him. With the ancient Navi Ring binding them and enemies closing in, Eva must choose: cling to her humanity or surrender to the night for a love that could damn her eternally.
