After initial contact with an alien entity leaves Kaylan unconscious, she wakes up to discover that she's now in command of the Athena mission stranded in a star system far from Earth.
The ship's computer is malfunctioning, and former hacker and astronaut trainee Zack Quick is the only one who can fix it. If he can't figure out what's wrong, they have no hope of getting back home.
In order to survive, the crew of the Athena must explore an alien star system to find the species that summoned them.
