During a live television broadcast on the night of a lunar eclipse, renowned astrophysicist Andrew Leland is suddenly lifted into the sky by a giant spacecraft and taken away for all to see. Six years later, he turns up, wandering in a South American desert, denying ever having been abducted and disappearing from the public eye.
Meanwhile, he inspires legions of cultish devotees, including a young physics graduate student named Shawn Ferris who is obsessed with finding out what really happened to him. When Shawn finally tracks Leland down, he discovers that he’s been on the run for years, continuously hunted by a secret organization that has pursued him across multiple continents, determined to force him into revealing what he knows.
Shawn soon joins Leland on the run. Though Leland is at first reluctant to reveal anything, Shawn will soon learn the truth about his abduction, the real reason for his return, and will find himself caught up in a global conspiracy that puts more than just one planet in danger.
