In a world in which the planets are run by a sophisticated clockwork solar system that connects everyday people to the Creator, a young clockmaker's apprentice is appointed by the Archangel Gabriel to rewind the Earth's Mainspring to prevent a disaster.

Author Henry Grady Weaver was convinced that human liberty is the mainspring of progress, and that government tends always to tyranny. In this book, first published in 1947, Weaver popularizes these themes for the American people. This is the Revised Edition first published in 1953, containing Weaver’s revisions discussed and agreed prior to his untimely death in 1949.
