Ada Lamarr may have gotten to the spaceship wreck first, but looter’s rights won’t get her far when she’s got a hole in the side of her ship and her spacesuit is almost out of air. Fortunately for her, help arrives in the form of a government salvage crew—and while they rescue her from certain death, they are not pleased to have an unexpected passenger along on their classified mission.

But Pleiti’s faith in her life’s work as a scholar of the past has grown precarious, and this new case threatens to further destabilize her dreams for humanity’s future, as well as her own.

The only thing she learned was that the Zone was no place for people. There were deaths, and the program was cut short. Now, they're sending her back in.

Dalton Greaves is a hero. He’s one of humankind’s first representatives to Unity, a pan-species confederation working to bring all sentient life into a single benevolent brotherhood. That’s what they told him, anyway. The only actual members of Unity that he’s ever met are Boreau, a giant snail who seems more interested in plunder than spreading love and harmony, and Boreau’s human sidekick, Neera, who Dalton strongly suspects roped him into this gig so that she wouldn’t become the next one of Boreau’s crew to get eaten by locals while prospecting.

But a demon is terrorizing the land, and now she's an adult (albeit barely) with responsibilities (she tells herself).
