Mistborn Era 1, Book 2
Killing the Lord Ruler was supposed to be the end. Now, with Kelsier dead and a whole world without leadership, Vin must embark on the next step to rebuild the new world. Together with Elend Venture, the idealistic young nobleman who loves her, Vin must try to put their world back together.
Protecting Elend against assassins keeps her sharp, but Vin is uneasy. The mists are behaving strangely and harbor a strange vaporous entity that seems to be haunting her. As armies rally around the capital, intent on conquest, Vin and Elend turn an ancient legend that tells of a power source called the Well of Ascension that bestows an unknown power to the one who wields it.
Killing the Lord Ruler was the easy part. Surviving the aftermath of his fall is going to be the real challenge.
