In an inhospitable galaxy, the planet Rosamond 6 is a rare find. With a moon, an atmosphere, and a thriving bio-system the world has all the keys necessary for human habitation. But while Rosamond 6 may look like an oasis among the stars, it harbors a fatal secret: the world is infested with the murderous xenomorphic aliens that have wiped out every life form in their path. Eager to prove her theory that the aliens can be reasoned with, anthropologist Jocasta Malvaux has set up an observation post on Rosamond 6. But when the monsters become aware of Malvaux and her expedition, something unexpected happens: the aliens don't attack. When Jocasta's son Rory races to the planet to save her, she won't leave. What is the secret behind the aliens' seeming lack of concern for the humans? Are the monsters evolving? Or is it simply a matter of time before every person on the planet is in a fight for their lives? The war is about to begin.
