Academ's Fury (Codex Alera, Book 2)

Academ's Fury - Jim Butcher Still loads of incredulous action and reasoning. Seriously, am I the only one who thinks that in case of an Emperor's temporary unavailability, there SHOULD be some established chain of authority? Instead we are given some shady "can't strust nobody" excuses, just for the convenience of the Author, who then happily throws some bunch of green kids in position of the highest ruler. Who happen know more about dealing with a crisis than both intellignece sevice's and royal guard's leaders.
I've got sore throat, because I couldn't stop myself from groaning every few pages.
The most frustrating thing is, I really care about what's going to happen to Tavi and I want to see it through. But I'm not sure if my sense of logic and believability can stretch to such lengths.
