Blood & Fire by George R. R. Martin

A lavishly detailed, in-universe history that traces the rise and turbulent reigns of a dragon-riding dynasty, from conquest and consolidation to incest, court intrigue and catastrophic civil war; assembled from annals, eyewitness reports and conflicting accounts, the narrative brings to life kings, queens and their dragons while showing how ambition, betrayal and the terrible power of dragons reshaped the political landscape of the realm.
