Stormwatch PHD: Unnatural Species

Picking up after the "World's End" collection, Fuji is in sickbay. The Engineer's nano-blood is trying to heal him, but no one knows whether he'll come back, and if he does, who will he be? Skywatch is attacked from within (by refugees who are really assassins) and without (by Kheran warriors who have been hiding on Earth for years). They must stand together to prevail, but when it's revealed that Tao has been influencing team leader King, that's a tall order.
