Parapsychology mind-games melodrama, bogged down in encyclopedic references to Castaneda, Gurdjieff, et al. Darwin Fall, 32, the great-grandson of early mind-theorist Charles Fall, is an editor of psi books, author of a very technical 2500-page opus; he's in contact with top Tibetan psychic Kazi Dama and superduper-psychic Jacob Atabet--who are being trailed by the KGB through California (Kazi easily mind-defuses the KGB hi-tech). And now Darwin has attracted the attention of Kirov, the supreme KGB occultist-psychic, who's hiding out in Vienna: Kirov suspects that Atabet and Darwin have tapped into his own spiritual school, that Darwin is the West's greatest student of the future evolution into ""luminous and eternal bodies""--a mutation ""of human flesh into the Earth of Hurqalya."" So Darwin meets Kirov in Vienna, goes with him to Moscow, and hence to the Well of Light in Samarkand. . . while Kirov tries to understand why Soviet cosmonauts are seeing angels, as is Chairman Rozhnov of the Committee of Science and Technology. Some esoteric, verbose fun, then, for psi believers with a spiritual leaning (experiments, theories, psychotronic generators)--but too weak on plot and character to interest most others.
