'In Shadows in the Stone Jack Dann creates a fully-realized, living, breathing universe, a universe where the Vatican is in Venice, Jehovah is really a lesser god known as the Demiurge, and the magus John Dee’s experiments with angels are true and repeatable. Here you’ll discover a nun who has the expertise and agility of a Ninja warrior, the reincarnated snake goddess known as the Daughter of Light, the famed Florentine magician Pico Della Mirandola, a young magus who is part stone, the Knights Templar of the Crimson Cross, the sapphire tablet: the most secret of the Dead Sea scrolls, and a 15th Century dirigible kept aloft by imprisoned souls. Here you’ll find wild adventure and Machiavellian subtlety, treason and heroism, love and carnality, joy and loss, magic, machines, the cosmic machinations of angels, demons, gods, and half-gods; and the absolutely breathtaking vistas that are their battle grounds.

'Join Jack Dann’s protagonists—Louisa Morgan and Lucian Ben-Hananiah—and the fellowship of The Dark Companions in their apocalyptic battle against the Demiurge—described in the forbidden Gnostic texts as the demon god Yaldabaoth… and known to us as Jehovah.'
