After feeling the starting chapters were a little slow (more interesting educationally than enjoyable entertainment) I found this adventure story quite enjoyable. This second book serves my introduction to the Kitty Hawk series, a character I find I like, although I suspect it might have been more useful to begin at the beginning.
Lots of interesting information is embedded in the story which is courageous as that can very easily weigh a story down and reduce the fun. I think the scales tip just in the right direction. Pleasing characters and the pacing of the adventure keeps the reader's attention enough.
