A singular evil. An unlikely salvation.
Captain Jared Carter and the Navy cruiser Hattan have helped liberate an alien race from the clutches of darkness, but at a terrible cost of lives and ships. While regrouping, they receive word that a shocking fate has befallen the Confederacy during the Hattan's distant campaign. Jared and his crew face the prospect that their home as they knew it is no more.
Danger now threatens them on two fronts: ahead, in the empire of the Domain, and behind, in the warring factions of the former Confederacy. The Hattan battle fleet must split up in hopes of combating both evils—their separate destinations leading to a singular enemy . . .
