Lily's dreams have always been haunted by a mystical stranger with green eyes until the day comes that she unexpectedly meets that stranger in a club. He's wealthy and handsome, but those traits aren't the ones that mark him as being not like average men. In truth, he possesses a surreal power and a set of angelic wings... An archangel turned outcast, Samael has wandered Earth for eons, unable to belong in either Heaven or Hell. However, he still holds a secret that both the angels and the fallen ones need to acquire at all costs. As soon as Lily meets Samael, her life is irrevocably altered. She herself is the secret at the heart of the war between angels and demons, and there's only one person who cares for her enough to try and save her from her fate: the exiled creature, Samael.
