The Dancers of Noyo

Like so many others before him, reluctant Sam MacGregor was sent on a pilgrimage for the Grail Vision by the Dancers: androids grown from the cells of one man, with the powers of hypnotism and illusion—androids who held the tribes of the Republic of California in thrall. But soon Sam began to doubt his own identity, for he experienced, in close succession, extra-lives in different corridors of time and space. And he could not know whom his search would destroy: the Dancers ... or himself.
