Demon Within is about a man whose sister is possessed by a demon seeking out a women who is a demon exorcist. When he finally finds her, she's not very willing to help him. So he pulls out all the stops to get her to help, including seduction.
But he's very wrong about this women, because she can see straight through him almost literally. She can see his aura so she knows a lot about his intentions, and thoughts.
This book was very fast paced short story. It has awesome characters, and a very interesting plot line. I kind of wish it could have been longer, but It was still very interesting as it was.
