December saw the best monthly sales yet for Fire and Blood, which is the book that the HBO prequel is based on. And the books, still active 'cos Martin is still writing them, have a huge following in their own right
I agree, the final season was botched. Dan and Dave couldn't wait to be finished to get out and into Star Wars, where they bombed too. Pity, cos all that character development over 7 years was just jettisoned for a quick, unsatisfying ending.
