Alien: Invasion (The Rage War, Book 2)

Lieutenant Johnny Mains and Private Gemma Lieder escape the Predator habitat where they were stranded and send Colonial Marine command a terrible warning: the Rage, a faction of human exiles, have captured a fleet of ancient colony ships and bred a vast army of Xenomorphs controlled by their android generals.

Within weeks the Rage reach the Human Sphere. With technology far beyond anything the rest of humanity possesses, their Alien armies sweep through the outer colonies, seizing dropholes and overwhelming Colonial Marine units planet after planet. Earth's envoys forge an unprecedented alliance with the Predators, while Major Akoko Halley and her Marines, escorting the scientist Isa Palant, are ordered to capture one of the android generals intact so that the secret of the Rage's control over the Xenomorphs can be unlocked.

Alien: Invasion is the second book of Tim Lebbon's Rage War trilogy, between Predator: Incursion and Alien vs. Predator: Armageddon.
