Lucas Adebayo grew up on a small mining ship in the asteroid belt, but wants to join the Navy and become the best pilot in the galaxy. The Navy has never accepted a Belter cadet before, but Lucas's skills secure him a place on the training ship, the Orpheus. Life in the Navy couldn't be more different than life in the Belt, and Lucas struggles to find his place. As a Belter, he's an outsider among his peers; as a Navy cadet, he doesn't quite fit in at home anymore, either. Lucas is caught between the worlds of his past and his future when a Belter rebellion puts everyone's lives at risk. Only he can lead the way to peace.
