Watch the preview below for the next episode of Game of Thrones, "Book of the Stranger."
Game of Thrones airs Sundays at 9pm ET on HBO.
Tyrion (Peter Dinklage) strikes a deal. Jorah (Iain Glen) and Daario (Michiel Huisman) undertake a difficult task. Jaime (Nikolaj Coster-Waldau) and Cersei (Lena Headey) try to improve their situation. Written by David Benioff & D. B. Weiss; directed by Dan Sackheim.
Summers span decades. Winters can last a lifetime. And the struggle for the Iron Throne has begun. It will stretch from the south, where heat breeds plots, lust and intrigues; to the vast and savage eastern lands; all the way to the frozen north, where an 800-foot wall of ice protects the kingdom from the dark forces that lie beyond. Kings and queens, knights and renegades, liars, lords and honest men...all will play the 'Game of Thrones.'
