The Well of Ascension : Book Two of Mistborn

The impossible has been accomplished. The Lord Ruler has been vanquished. But with Kelsier dead too, the awesome task of building a new world has been left to former street urchin and Kelsier’s protégé Vin, who is now the most powerful Mistborn in the land.

Vin is now worshipped as a hero in her own right, but since the death of the Lord Ruler, she is haunted by a strange vaporous entity hidden in the mists.

The siege of Luthadel rages on in the aftermath of the Lord Ruler’s defeat and only the legendary Well of Ascension offers 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.
