The stunning conclusion to the duology that began with the internationally bestselling Sun of Blood and Ruin, this Zorro reimagining weaves Mesoamerican mythology and sixteenth-century Mexican history into a swashbuckling historical fantasy filled with magic, intrigue, treachery, and romance.

They call her many things. Witch, Nagual Warrior, lady, Pantera. And after defeating the Obsidian Butterfly, Leonora carries a new title: Godslayer.

Peace in Mexico City is fragile. Rebellion brews in the North, and when the people's safety is at risk, Pantera must once again become the demure viceregent Leonora to stop a war before it begins. But her friends are scattered, Tezca is gone, and one wrong move could seal her fate. Caution is her ally, for the real Prince of Asturias--her former betrothed--has arrived at court, reigniting rumors that Leonora and Pantera are one.

A greater threat looms in the mountains, where a false king seeks to summon the god of night using a weapon of untold power. It's up to the Godslayer to confront this enemy. . . and the one growing within her. Only by embracing her divine origins can Leonora triumph over the forces of darkness--and maybe even spark a revolution that could change Mexico's fate forever.

But in doing so, she risks losing herself forever.
