If you’ve not already read George RR Martin’s brilliant series A Song of Ice and Fire, start now (US link).
If you have, get the new book, A Feast for Crows (US link).
I can’t recommend this series more. The books are:
- A Game of Thrones
- A Clash of Kings
- A Storm of Swords
- A Feast for Crows
- A Dance with Dragons (forthcoming)
- The Winds of Winter (forthcoming)
- A Time for Wolves (forthcoming)
Seek them out and enjoy.
