William M. Alnor investigates the intersection of UFO phenomena and New Age beliefs, exploring how extraterrestrial narratives have become integrated into spiritual and esoteric worldviews. Drawing on historical accounts and theological analysis, Alnor argues that the New Age movement has adopted UFOs as a modern manifestation of ancient angelic or divine visitations, reinterpreting them through a lens of spiritual evolution and cosmic consciousness. The book examines the theological implications of these beliefs and their impact on contemporary spirituality.

The book is regarded as a critical examination of the New Age movement's embrace of UFO phenomena. It is noted for its detailed analysis of how extraterrestrial encounters are framed within spiritual and esoteric contexts, often drawing parallels to religious experiences. The work is considered a significant contribution to the study of contemporary spirituality and ufology, offering a scholarly perspective on the integration of science fiction elements into belief systems.
