Since the tragic death of her parents in a car accident, Rosylin has lived with her grandmother in a rural province, in a countryside, deep within the woods-far from the city and the life she once knew. But ever since moving there, strange things have begun to haunt her nights. She began dreaming of crescent symbol blood tattoo, a man's voice calling her name, and a full crimson moon. And every morning, she always hear the sound of a raven outside her window. Since that, every morning there's a single black yet freshly bloomed rose was put in the side of the window, like someone left it there for her. One day, while visiting her parents' graves with her grandmother, something unimaginable happens. A person disguised in a long robe suddenly appears before her eyes-and in that very moment, her grandmother vanishes without a trace. As Rosylin runs to find her, a mysterious force pulls her into another world- a world she never knew existed-a world of immortals. Unknown to Rosylin, an ancient prophecy has already sealed her fate: she is destined to wed a prince- a vampire prince and her blood would bring prosperity to the vampire realms in Ambrogio, after centuries of bloodshed. Yet, the prophecy remains unclear-no one knows which of the two vampire princes she is truly bound to. As Rosylin unravels the mystery of her dreams, her bloodline, and her connection to the immortal world, she discovers that her arrival was no accident. Her heart holds the power to heal a broken realm... or to doom it forever.
