Two star systems.
One common enemy.

From the smoking rubble of war on a faraway planet, the surviving Centauries—our intrepid but haggard band of explorers—emerge, scarred by their terrible ordeal. But nothing is as it is supposed to be: Fond reunions bring bitterness, lies exposed confess their terrible truth; an alien planet becomes home, while home has become so alien. A new day reveals an unforeseen darkness.

Back home, Terrae Solaris is in peril. Risking everything against overwhelming odds, the Centauries set off on the final leg of their unenviable journey. But once again, discord threatens to undo them. Once again, secrets from their pasts place them in peril. Once again, Europa’s dark history conspires against them. And no one counted on the one factor that may undo them all: the enemy within.
