Lord of Chaos was the one with Rand locked in the trunk... Between that one and Knife of Dreams, there was a lot of (seemingly) pointless fluff - although, after KoD, I've regained my hope that RJ's vision is still intact and that, maybe, even the fluff had purpose.
As for New Spring - thoroughly enjoyed it. I really hope that he does manage - somehow, and after Memory of Light - to finish the other two prequels. Most especially the one he wants to write that tells Tam al'Thor's story.
Just how did he go from being a simple tabac farmer in the Two Rivers to a Blademaster in the Illian army... Got to be a good story there.
