Skip Crossroads of Twilight. Read the summary on Wikipedia. It's a gimmick that covers the same day and events from lots of different perspectives. None of them are good. That book serves as a slap in the face for the author who made a course correction for book 11 and got it back on track. Then Sanderson naturally has a faster pace than Jordan and brings it home strong. 11-14 are great again for those who survive 7-10.
