When I opened this book and saw there were no quotation marks (I mean "", not periods or commas), I was very concerned. No quotation marks remind me of Cormac McCarthy, who drives me nuts. But the book was very intense. I read it in one sitting!
The only thing I would change is the relationship between Jack and Saba. It felt a little forced. Other than that, great action and very fun. One of those few books that makes me want a sequel.
