Actually, Chalker manages to incorporate his favourite themes: that stagnation leads to Hell, his fascination with how much power corrupts, and what some call an obsession with transformation. If nothing else, his "first world" in this book brilliantly analyses what would happen if women really did have power. David Brin did an equally good (albeit different) job, and few others have avoided the standard clichés. As a conclusion to his most paranoid trilogy, the book is brilliant, up to the last chapter. Fans of the late Phil Dick (of whom I am one) should recognise it as the last chapter of Dick's own book UBIK. This lack of originality nonetheless fits in with one of the most paranoid trilogies I have ever read.
