This book is very interesting, covering a variety of topics from child abuse to in-depth discussion of fractals, love to culture, society to magic. Piers shows an acute knowledge of the scientific aspects of what he writes about. The book seemed to focus a little too much on helping Nona, and not enough about the MAIN characters, but this didn't detract from the book too much. The settings are varied, as always with Anthony, as are the characters. Anthony provides much insight to what Colene is thinking, which I think is the most interesting part of the book-- to see how she reacts mentally to things like stress, Darius, her parents, etc. There are heartwarming moments, and some interesting happenings back at good old normal Earth. Many different things happen, settings change quickly, minor characters come and go, but the plot runs smoothly enough and what the gang learns along the way is interesting and their adventures are still fun, sometimes amusing--they get stuck in one really odd situation in Nona's reality! If you read Virtual Mode and are interested in how Colene and Darius' relationship will grow and change, and how Nona plays into their scheme, and if Colene and Darius will EVER settle down back in Darius' home reality...this is a good book for you.
