The Invaders series brings time manipulation into Heppner’s military sci-fi formula. When aliens attack Earth, they bring technology that bends space and time, forcing human defenders to rethink everything they know about combat and strategy.
Published between 2016 and 2024, the six books introduce concepts like chronowarps and dimensional portals alongside more conventional space battles. The mix of temporal science fiction with military action gives the series a distinctive feel compared to Heppner’s other work.
