The Confederation and its allies have won their first victory, retaking their capital from the forces of the Hegemony. But the enemy is not beaten, far from it, and they are back, with an unstoppable weapon, a vast superbattleship, a deadly hybrid of imperial and Hegemony technology, called the Colossus. The great ship is enormously powerful, nearly unstoppable, and in its armored depths it hides a secret, another Hegemony weapon, one that will change the dynamic of the entire war.

Halo has been destroyed, and the threat it posed to sentient life neutralized. But victory has come at a terrible cost for the UNSC. Thousands of valiant soldiers fell in the battle to prevent the alien construct from falling into the enemy's clutches. Now, everything depends on the Spartan known as the Master Chief.
