I have read similar recommendations about the book and read it because of those.

The problem is that if you recommend the book for it's "unique plot twist", the reader will keep looking for clues on how the resution may not be the most obvious and figure it out pretty fast. Then it is actually no surprise at all anymore. At least this happenend to me.

It would serve the book better if it was recommended as a great (but traditional) murder mystery novel and that's it.
