Extinction Wars follows a familiar Heppner scenario — Earth under alien attack — but gives it a special forces angle. The protagonists are assault troopers, elite soldiers dropped into impossible combat situations against a technologically superior enemy.
Published between 2013 and 2018, the five books escalate from planetary defense to offensive operations in alien space. Heppner writes action sequences with military precision, and the series has strong appeal for fans of Starship Troopers-style science fiction.
