The Prophets are a leadership caste, and the Covenant looks to them with awe and reverence. To kill a Prophet would only increase Covenant hostilities with humanity – but to capture one could lead to a truce. Enter Master Chief and the Spartans! But even with upgraded armor and new tech, can Master Chief stop a Covenant invasion armada 700 ships strong? And if the Spartans fall, will the Covenant’s next target be Earth? Halo: Fall of Reach – Invasion concludes the adaptation of Eric Nylund’s novel Halo: The Fall of Reach, based on the international video game sensation.
