Lightless, by C.A. HigginsRead about the other entries on the list.
On board the ship Ananke, computer scientist Althea has a relationship with the ship’s artificial intelligence—and the AI is evolving into a sentient personality, complicating her work. As are the intruders, including handsome Ivan, who have somehow tricked the ship into letting them on board. One of them escapes into the ship while Ivan is being interrogated, but what worries Althea is how they got onboard in the first place—and what they’ve done to the AI’s code. What ensues is a pressure-cooker story, a locked-room mystery in which the room itself cannot be trusted to play fair.
Lightless is among Sam Maggs's five books about awesome women in space.
