There is another entirely different world separate from where humans reside. A forbidden relationship between these two worlds creates a female hybrid named Grey. She loses her memories and reunites with her mother's pack, but her life changes when she meets the fire wielding werewolf Jessica whom she feels oddly attracted to. It all starts when Grey's uncle, Ryan, makes her go to a supernatural safe haven called Blackburn Academy. She has to pass as a human; keeping what she is hidden from everyone she cares about. If not? The vampires that want the humans as food slaves will kill everyone she cares about in cold blood. The upcoming war has to be won, and for that everyone needs to know what she is. They will need her help, but will they ever be willing to accept it? The outcome in the end will be between prophecy and love.

'The boundary between Life and Death are at best, shadowy and vague. Who shall say where one ends and the other begins?' Cursed by the moon and trained to the bone, Athena was the perfect assassin. With every kill she made, her emotions disappeared, further succumbing to the life of a killer. With the blood of the beast, she determines everyone through their blood; the stench of it defines them as what they are - be it human or another, target or foe, innocent or pretentious liars. Her strength increases with each passing hour, slowly losing herself to the thrill of the hunt and the life of a killer. All was perfect until she made a mistake - one that almost cost her very life. Unexpectedly, she retained her life from the courtesy of Michelle Harper, whose blood she cannot define. Will this unexpected turn of events change her stone cold heart? Or will she let herself be consumed by the scent of her blood?
