Sabrina Jade lived during a time where vampires were the dominant species on Earth. The royal family controlled everything within the area and no one was brave or strong enough to go against their laws. Sabrina broke one of the laws the second she was born. She knew that it was illegal for her to be alive, so she keeps to herself most of the time.
Despite her efforts to avoid the outside world as much as possible, she gets taken away and forced to become a slave to the oldest son of the royal family. In the middle of trying to survive, she finds out that her soulmate, someone that she needs to live, is someone who despises her kind with every nerve.
There's nothing worse than loving someone you can't have.
