But as a slave, she could do none. One night, out of no where, a fire broke out and she was homeless. Wandering around the castle that was surrounded by the forest, Gabriel spotted her from bleeding head to toe. He's known as cold-hearted pureblood vampire but after encountering Tessa, something moved inside him. Could it be they were connected by a red string of fate? Could Tessa be his long-lost sister? Or are they lovers in their previous lives?
