Martin is nevertheless very aware of the subject, and when asked what he would have liked to change in his saga, he answers: "I don't know, I probably want to change more than one thing. Before adding, hilariously, if I could change one thing in one of my books, it would be to have finished them".
There are still two books missing to complete Game of Thrones, a delay such that even the TV series adapted from the work has already finished some time ago. After that, for those who are impatient, there are always the new spin-off series, as well as the book... of recipes.
