I love the novel A Song of Ice and Fire.
I haven't yet read the epic fantasy novel by George R. R. Martin.
I highly recommend the series if you enjoy the fantasy genre.
Have you read the 5th and most recent volume in the series? It's "A Dance with Dragons."
I have not, I've only recently started reading the series due to the TV show. 
The author's inspiration for the series came from Wars of the Roses.
So I've read. He was also inspired by French history novels such as The Accursed Kings by Maurice Druon.
The Accursed Kings
The Accursed Kings () is a sequence of seven historical novels by French author Maurice Druon about the French monarchy in the 14th century. Published between 1955 and 1977, the series has been adapted as a miniseries twice for television in France.
American author George R. R. Martin called "The Accursed Kings" "the original game of thrones", citing Druon's novels as an inspiration for his own series "A Song of Ice and Fire".
