Had quite a while to consider my rating on this book and why so much of it just did not gel with me. I never paid much in depth attention to the Amanda Knox story, so my knowledge of said story is just bare bones. So while this is being compared to that case or said to be the trigger for this novel, I have no way of knowing. What I know is that there were two women, college exchange students and one somewhat hunky neighbor, having relationships with both and than of course there is the murder of one of the girls and the other is said to have been the perpetrator.
So basically yes, this book does follow those lines, but where it deviated from the story I cannot comment. The writing in this book is very good, but something bugged me about it, not the story itself but the way it is written. I never really engaged with the characters or the story, never became emotionally vested in the outcome. Felt like it was just a story I was reading, or a recitation of facts without depth and only scratching the surface.
Anyway had a very hard time rating this, because on one hand the writing was very good and on the other, the style of the story just did not work.
Others may not have the same difficulty, it is certainly of popular interest and not all readers have the same reaction.
