Query: What was the point...?

I'm not quite sure what to make of this one. It kept my interest, but for a book that seems to be trying hard to come through with a message it's ultimately pretty empty. The characters were intriguing but there was little pay-off. I would like to have seen and understood more of Ellen.A thorn in my side throughout the book was the model Charlotte's fascination with "shadow selves." That just didn't ring true, for me. Charlotte was way too shallow and self-absorbed in every other way to have this single, uncanny insight into people.
