Xavir Argentum is rotting in gaol. Sentenced to life in the squalor of Hell’s Keep, punishment for an atrocity he didn’t commit, the once legendary commander is all but forgotten. His elite band of warriors are dead—and the kingdom he was poised to inherit is oppressed by the tyrant who framed him. For half a decade now, Xavir has ruled nothing but a prison gang. Yet vengeance comes to those who wait. When a former spymaster infiltrates the Keep, bearing news of his old enemy’s treachery, plans are forged. A few are compelled to restore peace—an exiled queen, an outcast witch, and an unlikely alliance of rogues and heroes. But peace and vengeance make poor companions. And first, Xavir must make his escape.
