An epic tale of sorcery, treachery, intrigue and supernatural strife set in 1600s London. Dr Sabian Blake - astronomer, scientist, and master of the Kabbalah, is in possession of the Zohar, an ancient leather-bound book which holds the secrets of the universe. Its mysterious inscription reads: 'Wormwood. . . the brightest star shall fall from the sky . . . and many will die from its bitterness'. Deciphering this prophecy could prove the key to saving London from a catastrophic fate. But there are others interested in the Zohar too - for more sinister reasons.
