The main characters are well realized and the scenes with Elizabeth and Joe are quite good, memorable, and do keep the book afloat. However, the plot is entirely unbelievable; it's as if London contains about 20 people--the figures in this book, all crossing paths, all knowing each other, all related in less than interesting ways. There is a sub-plot, which I could have done without; namely, mother and the vulgar rich American, of course, which did nothing to move the more interesting story along; that of Elizabeth and her past, dealing with her present and unknowable future. Also, a nit-picky thing: the volume I read contained too many typos and a couple of grammatical howlers. The book was that riveting that I noticed. I wait for the next and hope for better.
