The Bone Flower Trilogy

A darkness has taken control of Culhuacan, one of the Toltec's most powerful kingdoms. The bloodthirsty sorcerer god Smoking Mirror has sent her patron god - the benevolent Feathered Serpent - into exile, but the Feathered Serpent is determined not only to regain his sacred city, but also to end human sacrifice all together. Princess Quetzalpetlatl barely escaped Culhuacan with her life, but when the Feathered Serpent tasks her with helping his mortal son Topiltzin fulfill his divine mandate, she eagerly embraces her destiny.

Having defeated the sorcerer god Smoking Mirror and reclaimed her throne, Quetzalpetlatl and her brother Topiltzin set out to found Quetzalcoatl's new holy city and end human sacrifice throughout the Toltec world. But Smoking Mirror hasn't abandoned his own ambitions for power; with his allies - mortal and divine - threatening war among the gods, he's shifted his focus to Quetzalpetlatl and her budding magical powers.
