For years, Rheingard has entirely surrendered to the bloodthirsty beings that surround them. Once living in the shadows, vampires now reign over realms they've ruled for generations with ironclad authority. Among these powerful and merciless creatures is Anthea, part of the grand monarchy. As the king's daughter, she's known throughout the lands as the Princess of Valengar, her beauty matched only by her ruthlessness. The less fortunate are born into a caste system with no hope of escape. Humans are little more than resources, raised from birth to be providers, their blood and energy harvested for a variety of tasks. Among those destined for this bleak existence is Liam Blackwood, a young and strikingly handsome man chosen to serve the royal family. While others may resign themselves to this fate, Liam refuses to accept a future of subjugation. Despite the overwhelming dangers, he is decided not to surrender to the vampires' oppressive rule. Liam's defiance puts him at odds with a system designed to crush any sign of rebellion. The royal family has eyes and ears everywhere, and even the smallest act of resistance can be met with swift and brutal retribution. Yet, as he enters the foreboding castle where he is to serve, he clings to the hope that he can find a way out, a way to challenge the oppressive order that has held humanity captive for so long. It's a hope that could cost him his life or, if he's clever enough, give him back his freedom. "I'm sorry about this," the princess whispered, her voice almost tender. Liam promised himself that he would be the worst provider she ever had, that he would make her regret choosing him."

Rafe Ferreira, the spoilt son of an Italian millionaire, is banished to a small town for his troublesome behaviour. In his final year in a new school, he has one year and one chance to prove to his father that he is not a hopeless case and is a worthy heir to a fortune. Nora Fujioka is a small-town girl whose head is only filled with getting good grades. Her hard, no-nonsense attitude to studying makes her a social recluse and a major geek in school. She also happens to be the one person who can genuinely help Rafe. Initially, it doesn't help that they are polar opposites. She thinks he's an ungrateful slob. He thinks she's a mean stuck-up. But they learn more from each other than they originally bargained for.
