The Blighted Stars — Megan E. O'Keefe

When a spy is stranded on a dead planet with her mortal enemy, she must first figure out how to survive before she can uncover the conspiracy that landed them both there in the first place.

She's a revolutionary. Humanity is running out of options. Habitable planets are being destroyed as quickly as they're found and Naira Sharp knows the reason why. The all-powerful Mercator family has been controlling the exploration of the universe for decades, and exploiting any materials they find along the way under the guise of helping humanity's expansion. But Naira knows the truth, and she plans to bring the whole family down from the inside.

He's the heir to the dynasty. Tarquin Mercator never wanted to run a galaxy-spanning business empire. He just wanted to study rocks and read books. But Tarquin's father has tasked him with monitoring the mining of a new planet, and he doesn't really have a choice in the matter.

Disguised as Tarquin's new bodyguard, Naira plans to destroy his ship before it lands. But neither of them expects to end up stranded on a dead planet. To survive and keep her secret, Naira will have to join forces with the man she's sworn to hate. And together they will uncover a plot that's bigger than both of them.
