When a cyber-attack at NASA's flight center in Maryland disables the Hubble space telescope and the Nobel prize-winning scientist in charge disappears, the only clues left are a cryptic countdown clock and a chilling message displayed on the missing man's computer: Mankind Must Look No Further.
FBI Agent Joe Shepherd discovers a note in the scientist's handwriting that reads "e;end of days"e; as well as further evidence linking the attack to strange events eight months earlier: an explosion at the Citadel, an ancient monastery in Turkey; a viral outbreak that occurred in its wake; and the disappearance of a journalist named Liv Adamsen and ex-special forces operative Gabriel Mann.
Shepherd's investigation leads him to the secrets at the very edge of the universe and also into his own past as the countdown clock continues. But what is the "e;end of days"e; and what does it really mean for mankind will it be Revelation or Devastation?"e;
