The International Space Station suddenly loses contact with Earth. When a NASA tech devises a way to restore the feed, the images that come through are unfathomable: a scene of terrible violence, the crew unresponsive, droplets of blood hovering in zero gravity. But which of the astronauts on board would have done such a thing? And why? Off the coast of Mozambique, former special ops pilot and current treasure hunter Ethan Cain sees something he can't believe: an object shot out of the heavens plunging deep into the Indian Ocean. When he goes to investigate, it becomes even less intelligible. A space capsule has crashed into the sea, and inside is a woman alone, unconscious, and injured. Ethan knows he must save her. What he doesn't know is who she is, how she got there . . . or why she's the only survivor of a killing spree conducted 254 miles up in the sky.
