I got through the first five (maybe 6?) books and then just totally lost interest because nothing was really happening, and then the main character spends most of a book wandering through "the between world" or whatever. Perrin who had been one of the three main original characters (spoiler) turns out to be sort of a werewolf gets one totally random, token chapter about wandering through the forest on a snowy night or something.
Very strong start, along with the next two books but yeah, I agree with GP just kind of wanders off and the plot stalls out. Maybe some day I'll have time to pick these books up and see if the other guy was able to tie things together.
