Just finished Feast for Crows (4th book, 5th releasing next month). All I can say is, my god, Martin knows how to destroy a series.
Food, mud, trees, ****, *****, blood, gore and vomit. It might be an exaggeration but the author spends 90% of his last book DESCRIBING these things. Not saying how things happen, but describing it. Colour of mud, how the wind sends vomit flying in the wrong direction, the material chamber pots are made of etc.
Seriously, the TV series makers are going to come to a shuddering halt when they come to script this book.
