Warbreaker, Paperback Book, By: Brandon Sanderson

In the world of Warbreaker, each person is born endowed with the power of one Breath which can be sold and collected by others, then used to Awaken objects and even corpses to do their bidding. A few individuals who die in glory as gods, with the power of thousands of Breath, but no memory of their mortal lives and are enthroned in the Court of Gods in Hallandren's capital. To Vienna and Siri, princesses of Idris, the abuse of Breath and the claim of the ed to be gods are repugnant blasphemy. But with one princess wed to the God King of their nation's enemies in a bid for peace, the other finds she must rely on Breath-using mercenaries to try to rescue her sister from her monstrous husband.
