I was able to polish off the final book in Butcher's Codex Alera series. I still believe the series peaked in the middle, but this ultimate book was more entertaining than the previous one. I think the magic became a little pedestrian and there wasn't enough other stuff to fill the void. The middle books had some good military action that the later books lacked.
I also wasn't as interested in the romance in this book as it felt a bit forced.
Still, the series is entertaining and fairly innovating so I recommend this book and Jim Butcher in general.
