Endgame is the third and final novel in The Dead Planet Series.
After returning to Mars, Serus discovers that things aren’t quite the way they were when they left almost two years before. Thanks to their efforts, the answer to Mar’s salvation has been safely delivered, but bad news travels fast. Serus learns that Harris has been abducted and Midican has been destroyed. Knowing what is at stake, he vows to return and save his friend before his enemies can take another life of someone he cares about.
With a renewed sense of justice, Serus and his friends must return to Earth to finish what they started; to stop The Syndicate once and for all.
