 Due to what they call a 'racial mental block' a quasi-immortal race called the Isi are unable to prevent a galactic catastrophe. The Isi think humanity (specifically Peter) will help them overcome this hurdle, hence the book's opening line "Peter, we are losing Armageddon..." Unless he joins forces with them "... the galaxy is doomed...!" While Peter (and the reader) is understandably skeptical, the talking cat, as well as a crash course in telepathy rapidly convince him of Meg's sincerity. Soon he is using his uniquely human perspective to unveil new applications of ancient Isi mental powers, and develops some startling new abilities. Armed with complete control of his cellular structure (which allows for slow but complete cellular metamorphosis), and a "gnNäáq" (knack) which allows the mental manipulation of electrical energy, Peter and Meg travel to Meg's home planet of Isis where he will be taught the "mMj'q" (Magic) necessary to help save the galaxy from its impending destruction. Writing in what can only be described in a "Heinlein-esque" style, Palmer deliberately plays with sci-fi conventions. For example he implies that common terms such as witch, familiar, and magic actually stem from alien words. He also turns several clichés on their ear, giving the reader a trip through the protagonist's ego as he travels across a decidedly hostile planet.
