For some additional fantasy options that were enjoyed by a fellow Sanderson fan:
I will never miss an opportunity to plug Joe Abercrombie, The Blade Itself and the others in the First Law series are excellent and will get you about 10 books worth of excellent stories.
Chris Buehlman's The Blacktongue Thief is also quite good and the third in the series after the first book and a prequel come out later this year.
Red Rising and the following books in the series by Pierce Brown are very good and very popular.
James Islington's Hierarchy and Licanius books were quite good.
