Someone tried to destroy the Earth. They nearly succeeded, just missing and shattering our Moon. Huge fragments hit the Earth. Millions died. Four surviving starships were converted from exploration to military use, and sent out on a journey taking them farther into the galaxy than any humans had ever gone before. The goal: find the race that tried to destroy them. The mission: revenge.
