Publisher's Summary:
Continuing the saga of the award-winning Xbox game....This is how it began.
It is the year 2524. Harvest is a peaceful, prosperous farming colony on the very edge of human-controlled space. But we have trespassed on holy ground, strayed into the path of an aggressive alien empire known as the Covenant. What begins as a chance encounter between an alien privateer and a human freighter catapults mankind into a struggle for its very existence.
But humanity is also locked in a bitter civil war known as the Insurrection. So the survival of Harvest's citizens falls to a squad of battle-weary UNSC Marines and their inexperienced colonial militia trainees. In this unlikely group of heroes, one stands above the rest: a young Marine staff sergeant named Avery Johnson.
