Fire and Blood (A Targaryen History #1) by George R.R. Martin

Queen Visenya rose and stalked from the hall without the king'[s leave.

That night she mounted Vhagar and returned to Dragonstone.

When her dragon passed before the moon, it turned as red as blood.

The thrilling history of the Targaryens comes to life in this masterly work by the author of A Song of Ice and Fire, the inspiration for HBO's Game of Thrones.

With all the fire and fury fans have come to expect from internationally bestselling author George R.R. Martin, this is the first volume of the definitive two-part history of the Targaryens in Westeros.

Centuries before the events of A Game of Thrones, House Targaryen - the only family of dragonlords to survive the Doom of Valyria - took up residence on Dragonstone. 
Fire and Blood begins their tale with the legendary Aegon the Conqueror, creator of the Iron Throne, and goes on to recount the generations of Targaryens who fought to hold that iconic seat, all the way up to the civil war that nearly tore their dynasty apart.

What really happened during the Dance of the Dragons? Why was it so deadly to visit Valyria after the Doom? What were Maegor the Cruel's worst crimes? What was it like in Westeros when dragons ruled the skies? These are but a few of the questions answered in this essential chronicle, as related by a learned maester of the Citadel.

With all the scope and grandeur of Gibbon's The History of the Decline and Fall of the Roman Empire, Fire and Blood is the ultimate game of thrones, giving readers a whole new appreciation for the dynamic, often bloody, and always fascinating history of Westeros.
