Set in a complex and sprawling universe, the Eternity Series follows several key military and political leaders as they navigate the Second Galactic War from its accidental beginning to the stunning conclusion that will radically alter life throughout the galaxy.

In Eternal War, the four allies return to their home nations and return to their status of enemies. As Sabine moves away from the others and becomes obsessed with reestablishing her own nation, Damien becomes isolated in Lohen and faces increasing difficulties in his home nation. Only Mat and Adrian seem to be able to straddle the line between friend and enemy as they struggle to keep Sabine and Damien from drifting too far apart. But will they be able to keep Damien and Sabine from worsening the Second Galactic War?
