Initially I wasn't really interested in the premise of a wronged wife getting her revenge - it just sounded unpleasant. However, the style of writing really started to suck me in, and I could feel my heart speeding up with anticipation about what would be revealed... I also like the ambiguity of the narrator's situation. She sounds rational and normal in her descriptions of events, but she is clearly not coping and she obviously has issues of her own. I'd love to read the rest.
