" Aria wasn’t alone in her plans, either. The witches from my army had assisted her, setting things into motion to free her from my grasp. Siobhan, a powerful witch in her own right, had spelled another witch to attack Aria while we’d been in camp. The assault had led to Aria removing her rib, which held my mark and name. "
