Racing against the clock and against the better judgment of their parents and allies, Carol and Johnny head for the Above, the heaven of the sun god, to retrieve the lost soul of their cousin Stephanie before she becomes a cihuateotl, a fearsome ghost that haunts the evening skies. Their desperate trek lands them in the midst of a massive civil war in heaven, as a former sun god Huitzilopochtli leads rebels against Nanahuatzin Tonatiuh, trying to wrest away control of the sun so he can set the earth’s atmosphere on fire. The twins will have to forge a fast alliance among harpies, phantoms and ancient vampires if they’re going to stop the destruction of all they hold dear.
