The story of identical twins with ESP was immediately interesting to me, but the story turns out to be more about family and compatibility. I have read most of Sittenfeld's novels and haved enjoyed each of them. Her prose is very down to earth as if she is relating the information to someone already in the know, rather than trying to shock you with twists or arcs in the story. Sittenfeld keeps the story moving along with actions or dialogue, rather than delving too deeply into any one characters' psyche. It was interesting to spend a few years in the lives of these characters and the reassurance that while we all do selfish and stupid things, there are still people out there that accept and love us.
