Fact into fiction? In bestseller Strieber's engrossing SF thriller, which draws heavily from Communion
(1987), the author's controversial account of his personal contact with aliens, Danny and Katelyn Callaghan are a happily married couple oblivious that both took a saucer ride as kids—until a UFO sighting in their Indiana town awakens subliminal memories and excites their genius teenage son, Conner. Meanwhile, in a secret facility in Colorado, Air Force Lt. Lauren Glass learns that the Roswell incident really happened, and that for decades the surviving ETs have been sharing their advanced science with us. In exchange, these "Grays" have sought to rejuvenate their dying species by genetically manipulating human receptacles for their DNA. But some military hard-liners see this as a betrayal of humanity, and they launch a manhunt that brings them to Indiana and the Callaghans' doorstep. Though Strieber's human characters are sometimes as stiff and unbelievable as his Grays, his depiction of black ops intrigue and military espionage is a first-rate exercise in literary paranoia. It goes without saying that his abduction scenarios have a disturbing authenticity that even skeptical readers will find provocative. (Aug.)
