Continues the stories of the first volume, of course.
Even if the books are coming out at a rather brisk pace, the sheer amount of storylines and characters made this a bit hard to follow, but a fun read anyway.
I pecially loved reading it on Kindle and having Wikipedia right there for terms, so 'oh, right, this is in Turkmenistan' and 'so there were only eleven cardinals, wonder how that works out...'.
