From Publishers Weekly

Sanderson's entertaining second Mistborn novel begins after most fantasy series end, when the team of brave and cunning heroes find that holding on to power is even harder than overthrowing the previous tyrant. Elend Venture, the scholarly new Lord Ruler of Luthadel, clings to power while Luthadel's aristocrats and merchants grumble and two enemy armies—one led by Elend's father, Lord Straff—camp outside the city gates. Fortunately, Elend can rely on help from his lover and unofficial court assassin, the young allomancer Vin, but her magical metal-using ability makes her a target. An orphan of decidedly low origins, Vin is also having trouble adapting to her position as royal consort, especially since the underclass skaa, newly freed by Elend, look to her as their protector. Meanwhile, the ancient evil known as the Deepness is rising once again. This entertaining read will especially please those who always wanted to know what happened after the good guys won. (Aug.)

In the Mistborn trilogy's middle book, the great revolution's leader is dead, his apprentice Vin is overwhelmed by his legacy, and the idealistic new ruler is beset by those who want power themselves. Everyone wants to find the overthrown despot's Atium supplies, and armies besiege Luthadel. On patrol one night, Vin sees a figure apparently made of mist. The history of Kwaan, who helped the despot to power, emerges, portending a terrible power. The Well of Ascension may furnish resolutions to all these situations, but someone must find it. Vin's struggles with love and power inject the human element into Sanderson's engaging epic. Schroeder, Regina
