Over at “Not a Blog”, George R. R. Martin again mentions the Meereenese Knot, which is an especially problematic section of the book which has been puzzling him for a good while. Writing that he’s taking another hack at it, he mentions that he’ll split two large chapters into four smaller chapters so that he can change the order of events somewhat.
In comments, he also adds that he’s hopeful there’ll be news about a new A Song of Ice and Fire calendar soon.
