Query: Disappointing

I thoroughly enjoyed Anita Shreve's books The Pilot's Wife and The Weight of Water; I was quite disappointed with this, her newest book. The dialogue between Thomas and Linda did not ring true (it's hard to believe that people really talk this way). The letters back and forth do not distinguish one author from the other. And worst of all, the revelation at the end was very predictable. I expected better from this author.
