Ren is shaken: the mother she had believed dead for years is alive—and, more than that, she is a necromancer. It was she who created the iron revenants, an army of near-unstoppable undead. If this force moves to attack, there will be no one to stop it.
Fleeing the pursuers from the House of Bones, Ren, along with Julian and Leo, finds themselves once again at the edge of the Gash. Their goal is to destroy the magical well that powers the Queen of Corpses and allows her to raise the dead—before the uprising becomes irreversible. But acting together isn’t easy: Julian still can’t forgive Ren for her betrayal.
Ren will have to learn whom she can trust to avoid falling into a new trap. Because the danger comes not only from the dead—among the living, there will be those capable of striking you in the back.
