From the Dust Jacket:
"At the opening of this astonishing novel, a Nobel Prize-Winning physicist at a renowned California think tank is found murdered. The local police routinely move in, but soon, other, more menacing officials surround the institute.
It turns out that the physicist had kept diaries, and the diaries document his decade-long quest to confirm unidentified flying objects--UFO's. The papers are secretly passed to a young sociologist names Nick Schrader, who is amazed to learn that they describe in detail a secret scientific group, which sought to prove that the UFO craze of the 1950s and 1960s was not mass hysteria--that there truly were visitors from outer space.
Schrader sets out on a curious and dangerous odyssey: to track down the early associates of the physicist and solve the riddle of the diaries. As the interviews progress, he becomes aware of the increasingly desperate machinations of CIA and FBI agents, who for years had been trying to suppress the news of the signals from space.
Suddenly, colleagues of the physicist begin to die mysteriously. Schrader follows the diaries to their remarkable conclusion, and in a scene of spectacular beauty and horror in the Arizona desert, he ultimately learns what the diaries truly contained.
Deborah Deutschman spent four years writing Signals. Her extraordinary prose and research combine to create a spellbinding narrative in which disbelief is suspended, and scene after scene of beauty and strength evoke the wondrous possibilities of visitors from outer space.
Through this is a work of fiction, the scientific aspects are all accurate and based on fact."
