I really enjoyed the book and found the story interesting and well-constructed. I did find the writing style a bit awkward, but that may be because I’m Canadian and this is written with a distinct Irish flavour. I did notice a strong need for a good edit, but I didn’t let that distract me from an otherwise good story.
I know nothing about psychology, so perhaps a trained psychologist might be able to find flaws in the technical aspect of the story. For me it felt real and authentic, but perhaps a bit rushed.
The love interest and sex scenes were an unnecessary distraction in my opinion.
I did find the unveiling of ending quite contrived, but it did serve to pull together the loose ends. I don’t try to predict the endings of thrillers and mysteries (maybe I’m alone on this), but I was surprised with the ending. Looking back, there were enough clues so you wouldn’t have to be surprised.
Overall a well done story that I would have no difficulty recommending.
