A Divine Comedy

After all the pure-hearted souls have risen to Heaven and the armies of Hell rise up; after the battle to decide the fate of the universe, the only thing left is a husk of what once was. And on this husk once known as Earth, an angel has been sent on a mission from God. And they cannot return until after its been complete. But while on this journey, the angel meets someone unexpected, a boy who does not know why he still resides on Earth. What these two have to teach other is great and they will define each other's lives for the rest of eternity.
