Caitlin Taggart is stuck on the Moon, unable to get home to her daughter on Earth, after international tension has led to a travel ban for Moonborn like her. She works as a regolith miner. She is offered an illegal asteroid mining job for a chance to get home. On the job, things go very wrong for Caitlin and her crew, with consequences that threaten Earth itself.
Leaving aside the handwavy physics poorly suited to a hard science fiction story, I found this novel unengaging. Apart from the well developed protagonist, the rest of the characters seem like cardboard cutouts, with actions dictated by “plot reasons”. While the scope of the story is ambitious, and the flashback scenes are well written, the whole thing doesn’t gel.
