(This was more of a 2.5 stars for me.) I was really feeling this at the start. It pulled me in immediately, and I thought I was going to be in for one hell of a roller coaster, but then it sort of fell flat in the second half. Once the POV changed, it felt stilted and unnatural, and while it made sense that Hannah would do and act the way she did, it just didn't seem to fit with the rest of the story. It felt almost like the author wanted to throw in a supernatural element in a story that didn't need it. It was a let down because the beginning of the story was so, so promising.
It has not thrown me off from reading more of Dickson's work though, because I'm currently reading 'Pictures of You' and enjoying it. So it goes to show that just because you may not 100% enjoy one piece of work by an author that you may enjoy something else by them.
