Myth-Taken Identity - Robert Asprin and Jody Lynn Nye

Someone is impersonating Myth Adventures hero Skeeve the Magnificent and racking up quite a debt and it is up to his ex-partner/mentor Aahz to settle the situation--involving a pack of shape changing mall rats and a would be world conqueror--any way he can. This second collaboration of the two authors is a good deal of fun and excitement. Nye seems to lend a higher level of prose and longer stories, yet I recall the earlier books as funnier and--being that they had Skeeve and Aahz together, playing nicely off each other--somewhat sweeter. Perhaps that exact magic can't be reinstated, even if the old team is resembled; at least give me the faux quotes introducing each chapter. Is that so much to demand?
