Recovering from their narrow escape from Echo, John and Shiloh regroup. With the help of survivors from the Odyssey Fleet and their trusted inner circle - the Group of Eight - they strike back at the Dorgan base responsible for the deaths of their friends and loved ones. What they find there will change everything they thought they knew about their enemy. Guided by mysterious dreams, Shiloh, John and the Group of Eight set out for the Inhabited Systems. There they must convince governments on the brink of war to set aside their tribal differences and band together against a common enemy set on destroying them all. While Shiloh prosecutes a desperate, preemptive attack against the Dorgans, John returns to where it all began - to the planet once known as Earth - in search of his lost wife and lasting peace. As the past and future collide, deeper truths are revealed, and with it, a treachery that forces another terrible choice - one that could mean his death and the annihilation of an entire race.
