Quest for the Invisibles
Subtitle: The Discovery of Unseen Craft and Beings that Reside in the Invisible World All Around Us
Author: Nik Hayes
There exists an entire world around us that cannot be seen. The human eye sees only about 2.5% of the electromagnetic spectrum, so a number of people are exploring the invisible world around us. Trevor James Constable was a pioneer who began this work in the California desert in the 1950s, photographing what he considered to be UFO type objects and biological creatures traversing the skies in the infrared spectrum. Inspired by this work, Nik Hayes has taken things further by recording both in the infrared and ultraviolet realms, with video in addition to stills. The results of his first few years of work, conducted in the U.K., are revealed in this incredible book. Includes 50 photos.

Camouflage Through Limited Disclosure
Subtitle: Deconstructing a Cover-Up of the Extraterrestrial Presence
Author: Randy Koppang
According to the author, from the 1940’s to the present time the U.S. government has involved itself in the deepest levels of secrecy involving an alien presence on the Earth. This book delves into these deeper levels and reveals exactly how and why this secrecy has been maintained.
Two key researchers are also interviewed. Melinda Leslie claims that the military itself is involved with the abductions of important contactees with the purpose of gaining information from them about alien technology.
Second is Bill Uhouse, who claims to have spent an entire 38-year career at the very heart of an Unacknowledged Special Access Project. He has made unofficial public disclosures about advanced technology and the goal of perfecting functional flying discs.
Recommended to those looking for that “next level” of proof, in addition to skeptics who might change their minds. Something is going on, and this book will tell you in large part, exactly what that something is.

UFOs Do Not Exist
Subtitle: The Greatest Lie That Enveloped the World
Author: Roger Leir
Foreward: Ph.D. Edgar Mitchell
“UFOs do not exist” are not the words of the author, but of government authorities. The evidence found here should once and for all expose this longstanding lie. Are alien beings capable of abducting humans and implanting objects into our bodies that we do not know about? The evidence is the implants themselves – tiny metallic objects of unusual composition, surgically removed from people who claim to have histories of alien abduction. This book presents the most advanced research on the reality of alien implants which the author, an actual doctor, had originally thought was nothing more than a joke. For the first time, revealed in this book, eminent scientists have made legitimate off-world claims and proven them with hard evidence.
Also covers worldwide sightings, an update on the amazing 1996 UFO crash case from Varginha, Brazil, and a revealing Foreword by Apollo 14 astronaut Edgar Mitchell. As this book was going to press, Dr. Leir passed away. We are grateful for his incredible work.

Extraterrestrial Entities and Technology Recovery and Disposal
Author: The Majestic 12 Group
Considered by many to be a Top Secret government document written by and for a secret U.S. group, MJ-12, in 1954, which was later leaked to the public. Contains detailed guidelines for military personnel to follow in the event of encountering and/or recovering extraterrestrial beings or crashed objects.
There have been heated debates about its authenticity over the years and evidence has been presented on both sides of the argument. Due to its shadowy origins, we may never know with certainty if this is a genuine document or an elaborate hoax. Worth reading and investigating for oneself.
30 pages • Size: 8.5×11 • stapled binding Booklet • Price: $9.00
