I read the whole series from start to finish about 4 times a year and you always discover new things, although I haven't figured out who killed Asmodean either. I am a little disapointed with Knife of Dreams, it kinda feels like he's just "joining the dots' in the plot but I was pleased that I had surmised most things correctly, like where Semirhage had been hiding out and who Setalle Anan really was and who Noal is, the list goes on. My fave book is The Great Hunt, not qutie sure why, probably because they still retain some innocence before they get all arrogant esp Rand. And it features lots of Loial and the bit where Rand's hurling fire at Machin Shin at Barthanes' and Hurin asked what was the fire and was it going to throw it at them makes me laugh every time.
