Halo: Envoy

Humanity has been forced to the brink of extinction. Deadly civil strife, the mysterious legacy of an ancient civilization, and a fanatical covenant of alien races threaten to destroy us. Once a legendary instrument of death, Master Chief John-117 has now become an unlikely symbol of hope. If humanity can emerge from the chaos of war and reclaim stewardship over a troubled galaxy, we may find the secret to our ultimate evolution.
