Penny Dreadful meets The Gilded Wolves in this breathtaking finale to the young adult historical fantasy Bones of Ruin trilogy for years, the elite secret society called the Enlightenment Committee has waited for the apocalyptic force known as Hiva to destroy the world as it has so many times before. What the Committee didn't know, however, was that Hiva wasn't an event it was a person. Iris Marlow. An African tightrope dancer with no memories of her past. A girl who cannot die. At least, she couldn't die. Until her own friends discovered her one weakness and murdered her once and for all. The world-ending threat she posed should be gone too, but there's one more Hiva out there, and unlike Iris, this one has no love for humanity. In her absence, this Hiva has taken it upon himself to judge if humanity deserves to live. But when it comes to Hives, the judgment is always the same. The ending is always destruction. And while Iris is dead, she's not gone and after the betrayal that ended her life as Iris, she is now out for revenge. The world's days are numbered. The Cataclysm has begun.
