The Night the Heads Came
There's no such thing as an alien – at least, that's what Leo thinks until he and his friend Tim are abducted one night. When Leo comes to, Tim is gone, and no one believes his story. After Leo sees a psychiatrist and undergoes hypnosis, even he doesn't believe his story. But then memories begin to surface, and when Tim suddenly returns, Leo knows they are in otherworldly, extraterrestrial danger.
