Let's see: - the characters are caricatures and for supposedly senior military officers, act like teenagers - worse than teenagers. - pretty much every cliche that the author can think of is introduced, regardless of whether it is relevant or not - the writing style can be charitably described as... simplistic.
This would be a great book for 12-13 year olds. For adults, not so much.
I soldiered through the first book, skimming pages at a time. I lasted about a quarter of the way through the second book before giving up.
