A Storm of Swords by George R.R. Martin

Of the five contenders for power, one is dead, another in disfavor, and still the wars rage as violently as ever, as alliances are made and broken. Joffrey, of House Lannister, sits on the Iron Throne, the uneasy ruler of the land of the Seven Kingdoms. His most bitter rival, Lord Stannis, stands defeated and disgraced, the victim of the jealous sorceress who holds him in her evil thrall. But young Robb, of House Stark, still rules the North from the fortress of Riverrun. Robb plots against his despised Lannister enemies, even as they hold his sister hostage at King’s Landing, the seat of the Iron Throne. Meanwhile, making her way across a blood-drenched continent is the exiled queen, Daenerys, mistress of the only three dragons still left in the world….But as opposing forces maneuver for the final titanic showdown, an army of barbaric wildlings arrives from the outermost line of civilization. In their vanguard is a horde of mythical Others, a supernatural army of the living dead whose animated corpses are unstoppable. As the future of the land hangs in the balance, no one will rest until the Seven Kingdoms have exploded in a veritable storm of swords….
