So I'm going to finish His Dark Materials soon, then I'll move on to the long awaited ADWD, and afterwards I have a choice of which series I'll tackle next, but I am really, really uncertain. I've decided to choose between these:

Gunslinger - Stephen King
Magician - Raymond E. Feist
Assassin's Apprentice - Robin Hobb
His Majesty's Dragon - Naomi Novik
Wolf of the Plains (Birth of an Empire) - Conn Iggulden

I love intrigue and realistic elements of the human psyche/philosophy in my fantasy. What do?
