As far as quality, this book falls somewhere between the first book and the third book (the third book being MUCH better than the first), which is not really a coincidence, since it falls between the first book and the third book chronologically, as well.
The curious thing about this series is how recent it is -- early 2000s -- yet it feels older -- maybe 1980s. I'm not sure why unless it is the lack of any technological reference.
