The Alloy of Law (Mistborn Saga #4)

From #1 New York Times bestselling author Brandon Sanderson, the Mistborn series is a heist story of political intrigue and magical, martial-arts action.

Three hundred years after the events of the Mistborn trilogy, Kelsier and Vin have passed into the realm of history and myth, and the world of Scadrial is on the verge of modernity. In the frontier lands known as the Roughs, the old magics are a crucial tool for those who establish order and justice.

One such is Waxillium Ladrian, a rare Twinborn, who can Push on metals with his Allomancy and use Feruchemy to become lighter or heavier at will. After twenty years in the Roughs, tragedy has driven Wax back to the metropolis of Elendel. Now he must reluctantly put away his guns and assume the duties of the head of a noble house. But when a gang of Allomancers turn to train robbery and kidnapping, Wax will soon learn that the mansions and elegant tree-lined streets of the city can be more dangerous than the dusty plains of the Roughs.
