Here is an interview of Brandon Sanderson by Leigh Butler. I have always liked how open Sanderson is about the writing process, and about his own work.
If you are not familiar with Leigh Butler, see her re-read of the Wheel of Time here. This is a good summary of the Wheel of Time, and I enjoy her insights on the work itself. Not sure it is worth starting from the beginning, because she has written a book’s worth of material herself. However, if you are mildly interested in catching up on the last few books before the finale (without actually reading them), this is a good method.
She is also reading and reviewing A Song of Ice and Fire here. This is not a re-read because she has not previously read any of Martin’s books, so her take is somewhat different. I am very surprised by how much she predicts correctly, and just how far off she is at times. Having read the books three times myself now, I have lost that surprised feeling, and its interesting reading someone’s reaction to key moments for the first time.
