The epic, final instalment in the New York Times bestselling Empirium trilogy from Claire Legrand.

Queen Rielle, pushed away from everything she loves, turns to Corien and his promises of glory. Meanwhile, whispers from the empirium slowly drive her mad, urging her to open the Gate. Separated from Audric and Ludivine, she embraces the role of Blood Queen and her place by Corien’s side, determined to become the monster the world believes her to be.

In the future, Eliana arrives in the Empire’s capital as a broken shell of herself. Betrayed by those she trusted, she fights to keep her power at bay —and away from Corien, who will stop at nothing to travel back in time to Rielle, even if that means destroying her daughter.

But when the mysterious Prophet reveals themselves at last, everything changes, giving Rielle and Eliana a second chance for salvation — or the destruction their world has been dreading.
