Starbreaker by Amanda Bouchet

THEY NEVER WANTED TO BE HEROES
Captain Tess Bailey and Shade Ganavan are still the galaxy’s Most Wanted, and with revolution in the wind and the universe on the brink of catastrophic war, the situation couldn’t be more desperate. Despite the Dark Watch scouring the known sectors for them, rebel leaders have handed the crew of the Endeavor a delicate and dangerous mission: break into Starbase 12 and free renowned scientist Reena Ahern. She’s the only one who stands a chance of tipping the odds in their favor for the first time in decades.

BUT PULLING OFF THE IMPOSSIBLE IS WHAT THEY DO BEST
The clock is ticking. But as their attraction builds and secrets are revealed, Tess and Shade must decide if they trust each other enough to execute this impossible prison break. They could change the course of history, but they’ll be risking everything… They’ll just have to tackle one crisis at a time.
