When empathic librarian Lilah receives a midnight summons from Professor Drusilla Saint Augustine, she and Raven Darbyshire, the last priest of a dying order, are sent to rural Alabama on a mission to retrieve a mysterious book. Behind the walls of an ordinary family home, they discover an extraordinary secret connecting a murdered priestess, a mysterious angelseed experiment, and forbidden knowledge.

This decades-old mystery could potentially rewrite the prophecy of the coming apocalypse or hasten its arrival. With her ability to sense emotions and energies, Lilah must piece together the past while grappling with visions of possible futures, navigating a world where angels can be created in laboratories and time might be negotiable. When they uncover a hidden chamber containing the last testament of Lady Cora, a revered astrologer, her reality-shifting formulas offer the possibility of changing the future and preventing the prophesied pole shift apocalypse.
