Wicked by Gregory Maguire has become a mini-cottage industry for the author. There is the extremely popular musical, two (and soon to be three) sequels and other novels based on a similar premise (reworking of well known fairy tales). While the basic concept of reworking older, well-known characters isn’t new (Phillip Jose Farmer did itfor years), Maguire works with secondary characters (who aren’t fully developed in the source material) and works his stories around them.
