Norton is a believer in psychometry — the study of history through extrasensory perception. But if psychometry is real, it's the most tangible element in this four-dimensional, pan-galactic quest which leads the "gentle fem" and "cubling" sensitive Ziantha to inhabit the recently buried body of Vintra of Singakok and stretch even farther backward into the watery kingdom of Nornoch to become D'Eyree of The Eyes. The object of all this astral projection is the Eyes themselves, a pair of focus stones whose value lies, presumably, in their promise of still further identities for the intrepid Ziantha-Vintra-D'Eyree. For the easily transported.
