Blumenthal's account of the life and work of Harvard psychiatrist John Mack, who studied alien abduction cases scientifically. Released in 2021, this book is credited to Ralph Blumenthal and is listed here under High Road Books. In the Atlas it sits within abduction reports, research, and scientific framing. Its value here is mainly case-centered, emphasizing a particular incident, witness set, or interpretive dispute rather than a broad survey of the whole field.
