The Guardians- Life and Death
Humanity exists in a gray area between good and evil, and inside this gray area are mysteries that cannot be revealed or comprehended. Humans don't know about the strange creatures that live in their world. To interact with other people and live normally, like a normal human. They're on a mission with humans. Reclaiming the souls of the dead can help protect people and keep the balance of nature.
Their patience will be put to the limit by Elize, a cool undercover lady who causes them trouble. If Elize doesn't fear death, how can Lucian, her Guardian Angel, keep her safe? Dark, an Angel of Death, must figure out how to keep her from joining the long line of lost souls who have brought them nothing but misery through the millennia.
Consider the consequences if Aza, the Angel of Mischief and one of the fallen angels, decides to step in.
If Elize is intransigent and Aza interferes, neither or both of the Guardians will be able to complete their mission.
