First published in 1987, when it spent four weeks on the New York Times Best Seller list, Intruders remains one of the most powerful and influential books ever written on the controversial subject of alien abduction. Building on the evidence presented in his seminal 1981 work, Missing Time, Budd Hopkins here focuses on the remarkable case of "Kathie Davis," a young woman from rural Indianapolis whose life was changed forever after a shattering, face-to-face encounter one summer night with non-human entities.

Little did Kathie know it, but her encounter that night was not by chance; she had not been in the wrong place at the wrong time. Like so many others before and since, Kathie had been selected by an intelligence that operates beyond the veil of our accepted reality. Its technology challenges our comprehension, its motives are murky. But its interactions with Kathie and others like her have provided consistent clues-even physical evidence-pointing to an agenda relating to evolution and survival ... but of whose species ... theirs, or ours?

Such was the popularity of Intruders that it was later adapted for television as a CBS miniseries of the same name, starring Richard Crenna and co-written by Tracy Tormé, (Fire in the Sky, Star Trek: The Next Generation).

Intruders is a classic in the literature that remains just as relevant today as ever-and just as terrifying.
