Kira is haunted by nightmares from her past, and she's been on the run ever since her discovery made her the target of the corrupt, the greedy and the powerful. She can trust no one but her family. Now, forced onto a motley exploration crew heading to the toxic, stormy planet of Vilor, she'd rather be anywhere else. They arrive to find an abandoned base with cryptic messages left behind by a former crew. Kira's budding sense of safety is shattered as she discovers that someone is on her trail, and she's on the run again.

Josh, a crew member Kira's only just met, ends up on the run with her. But he's hiding something, too. Is he safe? Does he have his own agenda? Is he the hunter? As the secrets of Vilor begin to unfold, the dark ambitions of the human heart unleash a race against time.
