well I have read quite a few psychological thrillers as about a year ago this was my favourite genre but they have never been as creepy as this !!! from the get go there was gripping tension and suspense. as the book went on the story was more and more twisty which I think is essential in any psychological thriller. however there was a few elements missing for me personally. at the end I thought that it needed to be tied up better and I finished it left with a lot of questions! it seemed to be wrapped up in only a few pages when it could have been done better in a couple of chapters. but that’s my only criticism!!
