Elementals: Hades' Corruption

"The world is like an enormous set of scales. When evil begins to outweigh good, angels cram themselves in on the lighter side. You can't see them, but there they are, restoring the balance."
When evil is on the verge of tipping the scales, four angels make it their duty to stop the corruption of Hades with the help of one Faye Morrison. On the outside, she seems like a normal college girl, but she will be the key to saving the earth from the dark side and maybe even an angel's heart.
