Machiko is working as a supervisor for a remote ranching colony. Unfortunately the planet where the colony is located is also used by Predators to practise hunt techniques. This is done by implanting the local wildlife with Aliens. Now the colony is in the middle of a war between Aliens and Predators and Machiko has to use every trick in the book to save as much as the colony as possible.
Nicely written book with a lot of action. Unfortunately I had read the story before (as a comic in "Aliens vs. Predator omnibus volume 1"), so there were few surprises.
