I love Jennifer Egan. I read her books in reverse order (starting with 'The Keep', then 'Look At Me', and then 'Invisible Circus'). I love that she explores different themes in each book -- all three are very different. 'Invisible Circus' gets a firm 3 stars from me. I loved the overall feeling of living in the world during a time of great change, but not being able to identify just what it is that is happening even though you still want to be a part of it. Still, she uses a lot of exposition and towards the end-- much of the story is told to Phoebe by Wolf (something that annoyed me in the Harry Potter Books, particulary the last one with Dumbledore telling stories of the past to Harry).
