In a last ditch attempt to save their race, humanity biologically engineered werewolves to fight against the invading vampires. Unlike their bloodsucking counterparts, werewolves can go walk in sunlight and while they don't have a vampire's telekinetic abilities, werewolves possess the ability to read minds and superior strength. None of this matters to Ambrosia, however. When she wakes up in a prison with no memories except for her name, she is stunned to find out about this supernatural war going on, one that she apparently played a huge part in. Her vampire captors claim she is a werewolf who has killed dozens of vampires and sentence her to life in a vicious labor camp. Ambrosia struggles just to survive endless work, starvation, beatings and worse. Raiden is a dhampyr, the child of a human and a vampire, who has discarded the prejudice of his pureblood comrades and managed to rise the ranks of the vampire military. Currently stationed at this prison, Raiden watches Ambrosia from afar and even begins to fall in love with her, helping Ambrosia survive her torture. Is she really the cold blooded murderer everyone says she is? Without her memory, she is a normal teenage girl trying to survive hell. Together, they try to formulate an escape plan. However, Raiden is keeping something from Ambrosia- something that would tear both of them apart. As the war outside the prison is still raging, even if the two manage to escape, there may be no place for a werewolf and dhampyr in what is left of the war torn world. Welcome to the prison of darkness.
