"Description contains spoilers for previous book in the series" Who is the Hero of Ages? To end the Final Empire and restore freedom, Vin killed the Lord Ruler. But as a result, the Deepness—the lethal form of the ubiquitous mists—is back, along with increasingly heavy ashfalls and ever more powerful earthquakes. Humanity appears to be doomed. Having escaped death at the climax of The Well of Ascension only by becoming a Mistborn himself, Emperor Elend Venture hopes to find clues left behind by the Lord Ruler that will allow him to save the world. Vin is consumed with guilt at having been tricked into releasing the mystic force known as Ruin from the Well. Ruin wants to end the world, and its near omniscience and ability to warp reality make stopping it seem impossible. Vin can't even discuss it with Elend lest Ruin learn their plans!

First Son Alex Claremont-Diaz is the closest thing to a prince this side of the Atlantic. With his intrepid sister and the Veep’s genius granddaughter, they’re the White House Trio, a beautiful millennial marketing strategy for his mother, President Ellen Claremont. International socialite duties do have downsides—namely, when photos of a confrontation with his longtime nemesis Prince Henry at a royal wedding leak to the tabloids and threaten American/British relations. The plan for damage control: staging a fake friendship between the First Son and the Prince. As President Claremont kicks off her reelection bid, Alex finds himself hurtling into a secret relationship with Henry that could derail the campaign and upend two nations. What is worth the sacrifice? How do you do all the good you can do? And, most importantly, how will history remember you?

"Description contains spoilers for previous book in the series" 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.
