I like this series, but I think Book 1, with its zany characters, was the best. I've enjoyed Books 2 and 3, but the characterizations are different. The female hotshot pilot continued with her potty mouth, but the other characters generally no longer featured the zaniness they had in Book 1. All three books feature cliffhangers, so be prepared. I understand that there is at least one more coming--I think that the biggest risk for the author would be carrying the series on too long. But what do I know? I still enjoyed it, and believe that it's a good read. We need to find out how it all comes out.
