*Dark portents cast troubled shadows through the seventh installment of Daniel Abraham's adaptation of George R. R. Martin's bestselling epic fantasy A Game of Thrones . High atop the Wall, in an unforgiving world of wind and ice, the bastard Jon Snow and the dwarf Tyrion Lannister, by rights mortal enemies, forge an unlikely friendship. In King's Landing, Arya Stark, embittered by the loss of her direwolf, gains an unusual dancing master-Syrio Forel, formerly First Sword of the Sealord of Braavos. While in Winterfell, young Brandon Stark, who will never walk again, learns that he may yet ride . . . and perhaps even fly.
