Stuff to Read While Waiting for The Winds of Winter is just that, books to read while we wait... might have to add some more books to the list. It's all books that GRR Martin has mentioned or is a similar feeling to ASoIaF. I added the first books in series when I could, a few Martin has mentioned specific books further along a series. Sometimes he only mentions an author so I just added a book by said author. (I used one of his blog posts as inspo https://georgerrmartin.com/notablog/2013/03/13/reading-recommendations/)
