Synopsis: "It is the 'Atomic Age.' In the year 2000, the world is divided into a number of power-blocs, the largest being Occidenta and Orienta. Everything, including civilian vehicles, runs on atomic power fuelled by uranium. The uranium is running out, however, and when an uprising in the Meditteranean threatens the supply of the little that is left, it appears that Terra is about to be plunged into another world war. Desperate to avoid this tragedy, Professor Ó Glarcáin, his friend Captain Spéirling and Spéirling's daughter Deirdre blast off for the moon (Luna), where the professor believes a bountiful supply of uranium might be had. Things are complicated by the misadventures of Marco, a dangerous but inept Oriental spy, but eventually Luna is reached, and contact made with the native Selenites. The Selenites, due to their history, have an abhorrence of atomic technology, and they agree to give Terra all their uranium; Terra also acquires a Selenite invention into the bargain—'Good Rays' (so-ghaethe) that remove a person's aggression and inspire a wish to co-operate and make peace. In the end, Ireland is honoured for its role in ending war on Earth forever, and for establishing diplomatic connections with our friendly extraterrestrial neighbours." —Jack Fennell
