Reaper

Celeste Evans has a pretty average life. That is until she gets into a tragic car accident that ends her life. When she wakes up she has no memory other than her name. Damned for the rest of eternity as a Reaper she now must collect the souls of those who die on Earth. However, when something starts killing off the Reapers, people start cheating death. Getting into head on collisions, getting shot and walking away like it was nothing. To make matters worse, the one being accused for this crime is Celeste's best friend. Celeste now has to find it, and kill it on her own or her friend will be killed for the crimes. And this thing is coming for Celeste next. But she knows one thing, she isn't dying for a second time.
