Search Worlds Without End

Half-breed human star navigator Jaqi, working the edges of human-settled space on contract to whoever will hire her, stumbles into possession of an artifact that the leader of the Rebellion wants desperately enough to send his personal guard after. An interstellar empire and the fate of the remnant of humanity hang in the balance.

Although this is published as part of Tor.com's Novella line, it is a novel of ~55,000 words.

Jaqi, Araskar and Z are on the run from everyone - the Resistance, the remnants of the Empire, the cyborg Suits, and right now from the Matakas - and the Matakas are the most pressing concern because the insectoid aliens have the drop on them. The Resistance has a big reward out for Araskar and the human children he and Jaqi are protecting.

But Araskar has something to offer the mercenary aliens. He knows how to get to a huge supply of pure oxygen cells, something in short supply in the formerly human Empire, and that might be enough to buy their freedom. Araskar knows where it is, and Jaqi can take them there. With the Matakas as troops, they break into Shadow Sun Seven, on the edge of the Dark Zone.

At the heart of the Dark Zone, a duel for the universe rages.

In an ancient Jorian temple, Jaqi faces John Starfire, the new ruler of the Empire. He has set all the worlds aflame in his quest to destroy humankind. Jaqi has sworn to stop him. Problem is, Jaqi isn't much of a fighter.

Meanwhile, the sun-eating cosmic spiders, the Shir, have moved out of the Dark Zone and are consuming the galaxy. Araskar knows that he must hold them back, but to do that, he has to give himself over to the Resistance, under the command of John Starfire's wife. And she wants him dead more than she wants the stars to live.

If Jaqi and Araskar can fight their way out, they can use a secret at the heart of the Dark Zone to free the galaxy, and end John Starfire's new tyranny. They lose, and every star in the sky will go dark.
