The Strange Angels continues the saga begun in The Floating Boy. Cloud and Terp sojourn in Hawaii and Australia's Northern Territory before settling into domestic life in Arizona. Yet memories of Xuan and the proximity of Terp's college roommate Dagmar intrude on their bliss and lead them to deeper metaphysical discoveries. Cloud pursues a career as a history professor, while Terp serves as a mainline parish pastor, until peculiar circumstances draw them toward a previously unimagined vocational partnership. Involvements with the scurrilous preacher T. C. Smith profoundly test and stretch their psychic abilities. Face-to-face encounters with the Old One provide answers and create more questions about the nature of this enigmatic being. And in response to the mystical gravity unintentionally generated when Terp and Cloud are together, a galaxy of extraordinary and gifted people come into their orbit.

Kenneth Alan Moe was born in Phoenix, where from an early age he experienced mystical events. At age ten he began writing poetry. His working life has included service in the US Army as an intelligence research officer and prisoner of war interrogator, and in the corporate world as an insurance investigator. Encounters with tragic and traumatic incidents in these careers led him to seminary and service as a mainline Protestant minister and denominational executive. Consistently underscoring it all, for more than half a century he has practiced the vocation of writer, evolving through pencil, pen, manual and electric typewriter, and computer to produce reams of fiction, non-fiction, and poetry. He and his wife Shelly live in Phoenix with their cats Oscar and Ollivander. Five grown children make their homes in Phoenix and Denver. Everyone in the family is a creative artist in one medium or another, from words to photographic imagery to dance. When asked about autobiographical elements in his novels, the author said, "The books are fiction, but I confess that small pieces of my life are embedded in various characters, male and female. In addition, some paranormal activities described in the novels were inspired by actual things that have happened to people I know as well as to me."
