"Mark O'Connell's compelling biography of lone wolf Air Force investigator J. Allen Hynek is a testimony to the complex nature of belief and its effect on the human condition." -- Leslie Kean, bestselling author of Surviving Death and UFOs "No serious study of the UFO phenomenon could be complete without a look at Dr. J. Allen Hynek. O'Connell has done a masterful job of interweaving the life of this scientist, star-gazer, and space pioneer with an engaging encapsulation of the UFO phenomenon. This is not to be missed." -- Jim Marrs, author of the world's top-selling non-fiction UFO book Alien Agenda "This book reveals why Dr Allen Hynek's fight for a UFO science needs to be understood and turned into a powerful momentum for change.

Hop on board the wild UFO comet ride of our lives." -- Bill Chalker, "UFO writer" and author of The OZ Files: The Australian UFO Story, Hair of the Alien, and UFOs and Government "In telling the life story of Hynek, the 'astro-beatnik,' O'Connell winds up with a stunning panorama of the UFO movement and its colossal impact on pop culture and modern science." -- Vice "A book that smartly refuses to simplify anything. The mystery of UFOs persists, as does the mystery of J. Allen Hynek. Yet thanks to Mark O'Connell, the latter is now a bit less mysterious." -- The Los Angeles Review "Tracing Hynek's career, O'Connell examines Hynek's often-ignored work as a professional astronomer to create a complete portrait of a groundbreaking enthusiast who became an American cult icon and transformed the way we see our world and our universe." -- The Guardian "Hynek's story is one that deserves to be written in the stars instead of stuffed in a filing cabinet in a basement, where O'Connell found much research material for this book.

O'Connell's book is a good step to making that happen." -- Shepherd Express "O'Connell's book also is notable as a methodical history of the UFO phenomena in America--a story so often overshadowed by the Roswell incident." -- The Millions.
