Seventeen-year-old Ana is a scoundrel by nurture and an outlaw by nature. Found drifting through space as a child with only a sentient android called D09, she was rescued by a fearsome space captain and the grizzled crew she now calls family.

But D09—one of the last remaining illegal Metals—is glitching, and Ana will stop at nothing to fix him. Her desperate quest leads her to steal the coordinates to a lost ship that could hold all the answers. Yet at the last moment, a spoiled Ironblood boy beats her to the prize. He has his own reasons for taking the coordinates, and he doesn't care what he'll sacrifice to keep them.

When everything goes wrong, Ana and the Ironblood become fugitives on the run. Now their entire kingdom is after them—and not everyone wants them captured alive. In a lost corner of the universe, they uncover dangerous secrets that will change their lives forever.

As a darkness from Ana's past returns, she must make an impossible choice: protect a kingdom that wants her dead or save the Metal boy she loves.
