Orn

Orn, a man-sized bird who belonged to the most advanced species ever to develop on this world. Unsurpassed racial memory enabled Orn's mind to reach millions of years into the past, and it was his presence that led the three humans and the mantas to open revolt. Determined to prevent man's destructive exploitation of this world, they must pit themselves not only against the creatures they wish to save from extinction, but also against the all-consuming greed of Earth's powerful authorities. As rich in scientific detail as it is in breathtaking excitement, Orn is a masterwork of the imagination and a tribute to the creative genius of Piers Anthony
