The warship Trouble Dog was built and bred for calculating violence, yet following a brutal war, she finds herself disgusted by conflict and her role in a possible war crime. Seeking to atone, she joins the House of Reclamation, an organisation dedicated to rescuing ships in distress. But, stripped of her weaponry and emptied of her officers, she struggles in the new role she's chosen for herself. When a ship goes missing in a disputed system, Trouble Dog and her new crew of misfits and loners, captained by Sal Konstanz, an ex-captain of a medical frigate who once fought against Trouble Dog, are assigned to investigate and save whoever they can.
