Beneath the Shattered Moons(1976)

Michael Bishop

Alternate title "And Strange at Ecbatan the Trees"

In the future, on the island of Ongladred, mankind has survived two enigmatic, civilization-destroying setbacks. Now a third holocaust is anticipated. The people fear destruction from invading barbarians, the reappearance of a semi-mythical sea creature, and the devious intervention of the neo-human Parfects.

This imminent disaster is very much the concern of Ingram Marley, a government spy sent to keep surveillance over Stonelore, a secluded haven and the center of free thought on Ongladred, and Gabriel Elk, Stonelore's resident genius.

While panic and fear rage outside, deep inside Stonelore the mysteries of life are pursued - reanimation of the dead, the invention of powerful laser weapons, and the secrets of "old earth" knowledge. Amidst harrowing dangers of sea battles and land invasions, Michael Bishop explores the transformation of Ingram Marley, a man caught in the middle.
