Query: Big letdown

I think Hoag's writing is fairly tight and she keeps the suspense moving along but the reading was simply not worth the final ending. One small cliched twist at the end does not justify over a thousand pages of reading (Between Night Sins and Guilty as Sin). The shame of it is that there were so many other interesting aspects of the story that could have been wrapped up but were not (vague here so as not to spoil): the role of other significant characters and leads that were developed throughout that led nowhere or were left unexplained. And how did these brilliant perpetrators become so clutzy in the end? On a second point, I don't object to the mixing of romance and thriller but this romance was a copycat of Night Sins with different characters: complete waste of time.
