I've been listening through all of the audiobooks since December and just finished this one. I never managed to get through the whole series as a kid, so this one was a first for me and Wow.
Safe to say after this one that the safe episodic status quo has been completed shattered, I know the series does a good job with serializing most of its big elements to be regular parts of the series like the chee and the elemist and krayak etc, but this one definitely feels like the start of the end game
