For a thousand years the ash fell and no flowers bloomed. For a thousand years the Skaa slaved in misery and lived in fear while the Lord Ruler reigned with absolute power and ultimate terror, a divinely invincible leader. Hope is long lost, until a terribly scarred, heart-broken half-Skaa in the depths of the most hellish prison and discovered he has the powers of a Mistborn.

A brilliant thief and natural leader, Kelsier will turn his talents to the ultimate caper: one with the Lord Ruler himself as the mark. Only he's not just planning the greatest heist in history, he's plotting the overthrow of a divine despot. Kelsier recruited the underworld's elite, the smartest and most trustworthy allomancers, each of whom shares one of his many powers, and all of whom relish a high-stakes challenge. But even with the best criminal crew ever assembled,

Kel's plan looks like a long shot, until luck brings a ragged girl named Vin into his life. Like him, she's a half-Skaa orphan, but she's lived a much harsher life. Vin has learned to expect betrayal from everyone she meets, and gotten it. She will have to learn to trust, if Kel is to help her master powers of which she never dreamed.

The impossible has been accomplished. The Lord Ruler -- the man who claimed to be god incarnate and brutally ruled the world for a thousand years -- has been vanquished. But Kelsier, the hero who masterminded that triumph, is dead too, and now the awesome task of building a new world has been left to his young protégé, Vin, the former street urchin who is now the most powerful Mistborn in the land, and to the idealistic young nobleman she loves.

As Kelsier's protégé and slayer of the Lord Ruler she is now venerated by a budding new religion, a distinction that makes her intensely uncomfortable. Even more worrying, the mists have begun behaving strangely since the Lord Ruler died, and seem to harbor a strange vaporous entity that haunts her. Stopping assassins may keep Vin's Mistborn skills sharp, but it's the least of her problems.

Luthadel, the largest city of the former empire, doesn't run itself, and Vin and the other members of Kelsier's crew, who lead the revolution, must learn a whole new set of practical and political skills to help. It certainly won't get easier with three armies – one of them composed of ferocious giants – now vying to conquer the city, and no sign of the Lord Ruler's hidden cache of atium, the rarest and most powerful allomantic metal. As the siege of Luthadel tightens, an ancient legend seems to offer a glimmer of hope. But even if it really exists, no one knows where to find the Well of Ascension or what manner of power it bestows.

Emperor Elend Venture, having survived only to become a Mistborn himself, struggles to find clues by the Lord Ruler that will save his world, while a guilt-consumed Vin takes on a task of ending the cosmic power of the Ruin mystic force.

After twenty years in the Roughs, Waxillium Ladrian is forced by family tragedy to return to Elendel, where he learns the hard way that the elegant streets of the city can be more dangerous than the dusty plains of the Roughs.

Three hundred years after the events of the Mistborn trilogy, Scadrial is now on the verge of modernity, with railroads to supplement the canals, electric lighting in the streets and the homes of the wealthy, and the first steel-framed skyscrapers racing for the clouds. When family obligations forced Waxillium Ladrian to forsake the frontier lands and return to the metropolis of his birth to take his place as head of a noble House, he little imagined that the crime-fighting skills acquired during twenty years in the dusty plains would be just as applicable in the big city.

He soon learned that there too, just being a talented Twinborn — one who can use both Allomancy and Feruchemy, the dominant magical modes on Scadrial — would not suffice. This bustling, optimistic, but still shaky society will now face its first test by terrorism and assassination, crimes intended to stir up labor strife and religious conflict. Wax, his eccentric sidekick Wayne, and brilliant, beautiful young Marasi, now officially part of the constabulary, must unravel the conspiracy before civil strife can stop Scadrial’s progress in its tracks.

The Bands of Mourning are the mythical metalminds owned by the Lord Ruler, said to grant anyone who wears them the powers that the Lord Ruler had at his command. Hardly anyone thinks they really exist. A kandra researcher has returned to Elendel with images that seem to depict the Bands, as well as writings in a language that no one can read.

Waxillium Ladrian is recruited to travel south to the city of New Seran to investigate. Along the way he discovers hints that point to the true goals of his uncle Edwarn and the shadowy organization known as The Set.
