Fish

The narrator of Poul Anderson's The Avatar, XIII, p. 124, had been a great, proud, blue and white salmon, hatching in gravel, thrusting to the sea, prowling, chasing, exulting, then, much later, swinging back home with many others, surviving predators, then scooping a place for her young.

The Summoner came and took her into Oneness where she was Fish. Each of these one-page chapters divulges a further hint of this transcendent process.
