Dictated through the mediumship of J.L. Kennon, Eros Urides describes his beautiful Martian homeworld where loving Martians, living the Christ-Life, enjoy a perfect Utopian Socialist Society.

Earth is becoming a menace to neighboring planets. The Martians are concerned. But rather than send invading fleets of heat-ray wielding giant tripods, the Martians want to help. Eros Urides, a dead Martian from the City of Urid (which is located adjacent to a reservoir just north of the equator), has sent his spirit as an envoy, to enlighten the millions of God's children on Earth who are enthralled in darkness.
