All Mirren ever wanted was to save her brother, though now that she’s seen the horror and beauty of the Dark World, Similis feels more suffocating than ever. Her heart broken and her power now stifled, she vows to live an ordinary life, but when the Boundary is breached and the lights that have shone for a thousand years begin to flicker, she knows must protect her home from the growing threat of the Praeceptor.

Even if it means leaving behind the brother she sacrificed everything for.

Because the warlord has brought destruction to their gates, and if Mirren doesn’t decipher the remainder of the Dead Prophecy, both Ferusa and Similis will fall to the Darkness.

And it isn’t just the Praeceptor who seeks to stop her. Leading his father’s reign of terror is the newly returned heir. Soulless, cruel, and set on vengeance, Shaw will stop at nothing to get what he wants—including destroying the woman he once loved.

To thwart Shaw and save Ferusa, Mirren will have to find the depths of her power and push herself to the edge of her humanity. She must decide once and for all, where the line between dark and light lies.
