After finishing the Uglies series, I stumbled upon this book in the library's online catalog. Bogus to Bubbly by Scott Westerfeld is a wonderful companion to the series. When an author creates the kind of complex world that Westerfeld brought to life in Uglies, Pretties, Specials, and Extras, he or she likely writes pages upon pages of backstory that cannot practically be included in the final work. Bogus to Bubbly reveals much of that backstory to the lovers of the series. How did he conceive the story? Where does he get ideas for all the technology that is supposedly five or six hundred years in the future? What happened to our current society in the five or six hundred years before the beginning of the series? So much of this is explained and it is such a fun little read.
