Heart of Granite by James Barclay is the first book in the Blood & Fire series. It’s more sci fi than I thought it would be, (as in…completely) but that doesn’t throw me off as much as it would have years ago.
War has torn the world apart, and there are no signs that the war is going to end anytime soon. Max Halloran is a hunter-killer drake pilot of the behemoth Heart of Granite, and if you were to ask the man himself, the best of the best. He is a part of Inferno-X, and his glamorous life consists mostly of getting praise, piloting his drake Martha, fighting the enemy, and sleeping with his girlfriend. He’s living the dream and partying hard, knowing that a drake pilot’s life tends to be brief. Either you die on the wing, or you Fall. But then Max hears something he shouldn’t, something that turns his world upside down. And he refuses to let it go.
