The book of you by Claire Kendal

"Like the bestselling novels of Gillian Flynn and S.J. Watson, The Book of You--an utterly original fiction debut--is a sophisticated psychological thriller that will haunt you long after it reaches its terrifying, breathtaking conclusion"--

It started really well. I felt it was really well written and the author made me really hate Rafe. There was plenty of suspense and a no time did I feel the book was unrealistic. My issue is that I felt the ending a bit lacklustre compared to the beginning. I would say I loved the first 2/3rds - evident by the fact that I read that much on the first day I got it - but the ending was a bit disappointing. All in all a good read, but not a favourite.
