Query: Good trip book

This was a typical "trip" pick up - rush into a store, see what's new, use the cover as a selection tool, and then head to the airport ..... Great to see that is was definitely not a waste of time! This book kept me awake during a flight I normally reserve for snoozing - not an easy task. Cox has an open text style of writing allowing him to get good character development while still pushing an interesting plot ahead of the reader. For someone who likes to mix their fiction with a bit of education, I enjoyed the balance that Cox tries to make between sharing science while not "dumbing" it too much so as it insults a readers intelligence. I am curious to see what he will turn out next. Bottom line - worth checking out.
