The Empire Of Ashes by Anthony Ryan

Set in a world where the captured life-blood of dragons fuels both miraculous alchemy and terrible weaponry, this installment follows scattered survivors, soldiers and schemers as empires collide and a fragile balance of power unravels. Old alliances fracture and rival factions race to control the last sources of draconic power, while key characters wrestle with betrayal, hard moral choices and the personal cost of wielding monstrous strength. The story builds to sweeping battles and wrenching sacrifices that force its protagonists to decide whether remaking the world is worth the human price.
