Sounds very good
The cover is usually the thing that draws me in and makes me want to read the blurb and this was no different. When I read the extract however I cannot picture Missy as the lady on the cover. Maybe she changes over the course of the book and it will be her but its not how she appears at the start. There's plenty of info in the first couple of chapters to make you want to read on and it seems to be written very well.
