They came from beyond the galaxy, with a single mission: to destroy us all. Once called aliens or gods, their power has crushed countless civilizations, and now they hunger for Earth. Marco and Addy, veterans of the Alien Wars, have retired to a peaceful life with their children. But as a new war looms—one that could devour the galaxy—Earth needs them again. From the brink of despair, heroes will rise to defend humanity. 4.4 stars, 145 ratings. From $0.99. Free via KU. SHOP NOW /
