I really appreciate the way Kloos structures the series. As a friend pointed out, he doesn't insist on pacing all books evenly; the previous one was relatively calm, then this one was all combat almost all the time. It makes for a more natural narration and I think it suits the series well.
I also really appreciate that he didn't use That One Last Thing At The End for a stupid cliffhanger, but made it into a satisfying resolution instead. That earned Kloos even more points in my book.
