The Well of Ascension (Mistborn Book 2) by Brandon Sanderson

"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 protege, 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 protege 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."

This book was not something I would normally pick up, and it took me awhile to get into it. But I finally did read the whole thing (all 592 pages). I enjoyed Brandon Sanderson's writing style and the world he created although I did find the story dragged in some places. The characters were interesting and well-developed. Even though I don't think I'll become an avid reader of fantasy, I am tempted to pick up the next book in series when it comes out just to see what happens next.
