Shaara is running out of friends.

The sacrifices she and Warden made two years ago bought the League time, not victory. The war against the Undying has left them exhausted, drained of everything but hope-and precious little of that. The simple fact is that the Undying are going to win. Warden knows it, Shaara knows it. The Undying sure as hell know it.

Until, out of the black, the Eternal comes to Shaara with an offer she can’t refuse, however much she’d like to. The threat he warned her about two years ago is real, and now it’s come calling. It cares nothing for their little war. All life in the galaxy, Undying or not, will end if it spreads unchecked. Shaara and the Eternal have little choice but to work together to destroy it . . . At least, for now.

But people on both sides aren’t happy with an alliance, however temporary. Some of them are willing to risk all life just for a shot at power-and revenge. If Shaara can’t find a way to defeat them, she and the few friends she has left will lose more than their lives.

They’ll lose everything.
