Lords of the Night

Where is Cclancy? The gods only know.
And they’re not telling. 
Armed with only the sketchiest of clues, Sierra and her demigod friend, Chaco, embark through time and space to look for Sierra’s fiancé in the Yucatan Peninsula of the ancient past. Once there, they encounter, Ix Mol, a pregnant teenager hoping to marry her slightly disreputable lover—if she can get to him before he is sacrificed to the god Chaak.
Treacherous priests, scheming spirits, and the motley monsters of Mayan mythology try to stop Sierra and her friends, but nothing slows them down until they encounter the Lords of the Night, the dreaded gods of the Mayan afterlife. 
If that weren’t bad enough, the evil avatar Necocyaotl makes an appearance to attack Sierra and Chaco at the moment of their greatest triumph.
“Lords of the Night” is the third and final book of the “Gods of the New World” trilogy, preceded by “The Obsidian Mirror” and “Fire in the Ocean.”
