I'm not really a big fantasy fan either, only read this and LOTR and the Witcher books. I enjoy psychological thrillers and "strange" books, e.g. House of Leaves by Mark Z. Danielewski and Waiting Period by Hubert Selby Jr. (all his books are quite strange).

However, I have never come across the depth and character development I found in Wheel of Time in any other book or series. Robert Jordan was a phenomenal writer.
