The Height of Pillar: Book 2 of the Great Cities

Kellen Wayfield is no hero. When old debts finally catch up with him, he’s forced to become one, or die. The long time swindler would rather disappear into the shadows of Darkwell and hatch his next con, but instead he must strike out into the unknown with his old friend, Deagan Wingrat. Entrapped into similar obligations, Deagan leaves his simple life to lend his sword and shield to Kellen’s cause. With his knighthood stripped away, he risks everything to protect the city that cast him aside.
Devenkai’s forces encroach on human lands with the inevitability of nightfall. With two cities remaining, only a man without honor has the power to choose: which one shall he feed to Devenkai first?
