A near future Earth is dying due to human interference; Tech-Green is doing its best to repair the damage and is insisting that humankind leaves the planet to give it time to heal. Ari Famber, is the result of a genetic experiment she knows nothing about. Leila Saatchi, a friend of Ari's dead father, has promised to find her and protect her from others who may seek to use Ari for their own ends. Leila's naturotech pagan group arrives at Taler's Bump, Ari's home, with the intent on awakening her latent, potentially world-changing potential. In Arcady city, a massive sprawl of geodesic domes, Zambia Crevecoeur has hit rock bottom and sells himself to a ruthless shady business woman who has him transformed surgically into a strange new creature. The neuro-engineer Tammuz Malamute who has a mysterious past, is called upon to repair Zambia's shattered mind. Leila's travelling group move towards Arcady where Leila intends to seek the help of her mentor, Quinx Roirbak. Unknown to her, Quinx is harbouring Tammuz Malamute, whose past is due to collide dramatically with the future, and the abilities stored in Ari's body. Hermetech is a dazzling mix of science and mysticism. First published in 1991, its messages and warnings are still relevant today.
