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. Kelsier, Vin, Elend, Sazed, Spook, and the rest are now part of history—or religion. Yet even as science and technology are reaching new heights, the old magics of Allomancy and Feruchemy continue to play a role in this reborn world. Out in the frontier lands known as the Roughs, they are crucial tools for the brave men and women attempting to 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, Wax has been forced by family tragedy to return to the metropolis of Elendel. Now he must reluctantly put away his guns and assume the duties and dignity incumbent upon the head of a noble house. Or so he thinks, until he learns the hard way that the mansions and elegant tree-lined streets of the city can be even more dangerous than the dusty plains of the Roughs.

Deadly storms have ravaged Mina’s homeland for generations. Floods sweep away entire villages, while bloody wars are waged over the few remaining resources. Her people believe the Sea God, once their protector, now curses them with death and despair. In an attempt to appease him, each year a beautiful maiden is thrown into the sea to serve as the Sea God’s bride, in the hopes that one day the “true bride” will be chosen and end the suffering. Many believe that Shim Cheong, the most beautiful girl in the village—and the beloved of Mina’s older brother Joon—may be the legendary true bride. But on the night Cheong is to be sacrificed, Joon follows Cheong out to sea, even knowing that to interfere is a death sentence. To save her brother, Mina throws herself into the water in Cheong’s stead. Swept away to the Spirit Realm, a magical city of lesser gods and mythical beasts, Mina seeks out the Sea God, only to find him caught in an enchanted sleep. With the help of a mysterious young man named Shin—as well as a motley crew of demons, gods and spirits—Mina sets out to wake the Sea God and bring an end to the killer storms once and for all. But she doesn’t have much time: A human cannot live long in the land of the spirits. And there are those who would do anything to keep the Sea God from waking…
