A Song Of Ice And Fire Book 3. - A Storm Of Swords Part 2 : Blood And Gold
George R. R. Martin

Jon Snow has infiltrated the army of the King-Beyond-the-Wall in search of the Horn of Winter that Joramun blew. Giants and the undead have woken from the earth at its sound. Ever closer, the dark flames of Targaryen dragons deliver death in the cities of Astapor as Daenerys approaches Westeros with vengeance in her heart. Still the wars rage across the blighted lands of the Seven Kingdoms. Set in a world of harsh beauty and powerful magic, torn by treachery and consumed by greed and ambition, this is the most awe-inspiring and compelling fantasy saga since The Lord of the Rings.
