I got mine through iBooks. I had it preordered and got an email that it was in and have been squinting at my iPhone ever since. I did find the kindle edition (linked).

Here is the eBook from Barnes and Noble. http://search.barnesandnoble.com/Distinctions/Robert-Jordan/e/9781429957892/?itm=1&USRI=distinctions

May I return from Heck now?
