It's also one of those books that just plunks the reader into a world, and the reader has to make some effort to deduce the way the world works via dialog and descriptions. Plus, people talk funny. I'm pretty sure I wouldn't pass a pop quiz on exactly who was related to who, or other major plot points. Someone more acclimated to this type of writing would probably have done better.
There's a great deal of edged-weapon warfare in the book, but the blood, gore and screaming horror is underplayed; it's more like one of those strategy games played in the back of the comic book shop translated into prose. The tactics, insofar as I could understand them, were clever, and served to let the good guys prevail over the bad guys in most cases.
