Christina is used to feeling invisible. Orphaned at the age of five, she can barely remember her parents. All that is left of them is a faint crumbled up picture and her mother's necklace, both left with her on the orphanage's doorstep. Passed around from foster home to foster home, the only stability in her life is her best friend, Sam. When a home finally seems possible, Christina finds her world turning upside down on her eighteenth birthday. Exactly who were her parents and exactly what is she if not human? Nicolas is next in line for the crown. His uncle has taken over since the King's passing, and once he steps down or his time comes to pass, it will be his responsibility to step forward. However, his world and that of the humans is in great danger. An army is being formed of those tired of hiding in the dark. They believe a world with them as rulers is far past due. Even though Nicolas has come to despise the mortals in his years of existence, he knows the only thing worse than their rule is the rule of his sister. But how on earth does his uncle think a swine of a girl such as Christina can possibly be their salvation?
