Sidney and Kylie have just found out they were adopted. Not only that, but their real mother is a fairy. Now, Sidney-a vampire/fairy hybrid-must go along with her sister and the love of her life, Cael, on an adventure where nothing is as it seems. Their mother has left them clues along the way and pieces of a gigantic puzzle to lead them to a realm unknown to all other humans. Meanwhile, there are unsolved disappearances in the mystical world, leaving the balance of good and evil in a constant state of change. Will it all come full circle in the end, or will they be left with more questions than answers?
