The devil you know or the one you don't? For the Demon Queen and her Rejects, things are guaranteed to get ugly whichever they choose.

While Olus works to prevent the Nephilim from engulfing the entire galaxy in war and the Rejects plot to escape from General Kett, Abbey finds herself trapped in an ancient Seraphim stronghold and surrounded by more enemies than she even knew she had.

Queenie is back and better than ever! Abbey's recent experiences have changed her, but is it for the better? She's learned the truth about the Seraphim, and General Kett's betrayal has left her to wonder if there's anyone outside of the Rejects she can trust. When the Nephilim begin their assault on the Republic and her daughter is caught in the cross-fire, she'll have no choice but to depend on Captain Mann to do what he can to help. As much as Abbey wants to go home, she has an entire galaxy to protect.

The most powerful starships ever constructed are taken. Thousands are dead. A fleet is in ruins.... Lieutenant Abigail Cage never expected to find herself in hell. There was a time when she was one of the most respected operatives in the military. Now, she's doing hard labor on the most miserable planet in the universe. Not for long. The Republic is looking for the most dangerous individuals it can control. The best of the worst, and Abbey is one of them.

The Confederation and its allies have won their first victory, retaking their capital from the forces of the Hegemony. But the enemy is not beaten, far from it, and they are back, with an unstoppable weapon, a vast superbattleship, a deadly hybrid of imperial and Hegemony technology, called the Colossus. The great ship is enormously powerful, nearly unstoppable, and in its armored depths it hides a secret, another Hegemony weapon, one that will change the dynamic of the entire war.
