irisin (Austria) (2008/03/19): The first one seperating Skeeve from his gang has him on Perv, which is a lot like New York, perhaps done by Luc Besson, looking for Aahz.
An interesting addition is a Djin and the explanation of how Djinger had hit onto the bottle idea. Like Aahz's mother, it is one of a number of introductions bound to reappear in later books.
In keeping with Asprin's own personal changes, Skeeve ponders the nature of friendship a lot, and who he himself is.
