Atmospheric Disturbances

I really wanted to like this book. It had such an interesting plot–man's wife is replaced with an exact (well almost exact) duplicate of his wife. Where did she go? Is he just crazy? In the end, however, I didn't quite understand what was going on in the book with the secret weather societies and all...and I was very much displeased that the book did not seem to resolve the story at the end. We finish still not quite knowing what happened to the real Rema, if anything happened to her at all.
