For millennia, Cassiel was a powerful Djinn-until she was exiled to live among mortals. Now the threat of an apocalypse looms, and Cassiel is in danger of losing everything she has come to hold dear…

As the world begins to fall apart around her, Cassiel finds herself fighting those she once called her own-the Djinn.

She knows that this might not be a battle she can survive, but protecting those she loves is worth any cost…
