Mistborn Trilogy Boxed Set - Brandon Sanderson

Once, a hero arose to save the world. A young man with a mysterious heritage courageously challenged the darkness that strangled the land.
He failed.
For a thousand years since, the world has been a wasteland of ash and mist ruled by the immortal emperor known as the Lord Ruler. Every revolt has failed miserably.
Yet somehow, hope survives. Hope that dares to dream of ending the empire and even the Lord Ruler himself. A new kind of uprising is being planned, one built around the ultimate caper, one that depends on the cunning of a brilliant criminal mastermind and the determination of an unlikely heroine, a street urchin who must learn to master Allomancy, the power of a Mistborn.
