Query: Not quite sure how I feel about this book

I am really torn between 2 and three stars, maybe 2-1/2? I was very excited to read this book, the description was exactly the kind of story I usually enjoy reading. It started off OK, then got better, then ended....I think I wanted more. I haven't read any of Jennifer Egan's other books, and if they are similar to this one, I don't think I will.
