Hey everyone, my name is Aaron and I have perused this board a bit but have never actually signed up. I'm a 23 year old Engineer/physicist from NC. I began reading Brandon's books after reading his WoT novels and thought that his Way of Kings was one of the best beginnings to a fantasy series that I have ever read. Now, having said that, I am hoping for some advice here... I recently purchased a first edition copy of The Well of Ascension and it is missing the pages 521-560 but has pages 561-590 printed twice... I don't have a way of returning the book but obviously I collect them and would also like to finish the book. Does anyone have any ideas on who I should contact to try and fix this?
