This compelling hardback guide looks afresh at key episodes of alien activity on earth, from sightings to encounters and other unexplained experiences, richly illustrated with full-colour images and photographs throughout.

From Roswell to Taizé, the book dissects fascinating eyewitness accounts of communication and contact with alien beings, as well as chilling cases of abduction. It also sifts through sinister evidence of government cover-ups. Alien Encounters provides in-depth analysis of the most important encounters, including:

• The pilot who saw 12 alien aircraft flying in a diamond formation

• The Exeter Incident - chased by UFOs in the darkness

• The Socorro Incident - solid evidence of alien activity

• Betty and Barney Hill - abducted on Highway 3 in New Hampshire, USA

Alien Encounters is a gripping investigation of strange events that continue to spark fierce debate. The Pentagon's decision in 2020 to admit the existence of its Unidentified Anomalous Phenomena (UAP) division has begun a new era in encounters between humans and extra-terrestrials. Understanding the meanings behind these strange events has never been more important. Strikingly illustrated with full-color photographs, images, and diagrams throughout.
