BackA Storm of Swords 1: Steel and Snow by George R.R. Martin - Book

The Seven Kingdoms are divided by revolt and blood feud, and winter approaches like an angry beast. Beyond the Northern borders, wildlings leave their villages as the renegade Brother Mance Rayder leads them South towards the Wall. Robb Stark wears his new-forged crown in the Kingdom of the North, but his defences are ranged against attack from the South, the land of House Stark's enemies the Lannisters. His sisters are trapped there, dead or likely yet to die, at the whim of the Lannister boy-king Joffrey or his depraved mother Cersei, regent of the Iron Throne. And Daenerys Stormborn will return to the land of her birth to avenge the murder of her father, the last Dragon King on the Iron Throne. Suitable for adults
