When the newly-released demons set the Order of the Crow an impossible ultimatum - deliver the Philosophers Stone or suffer fatal consequences - alchemist's apprentice Donna Underwood must recreate the mythical artefact before the world is plunged into a modern Dark Age. But will she succeed when she finds herself pitted against a vengeful demon king, two faerie queens, an immortal magus and her own dangerously unpredictable powers? Donna must be willing to make the ultimate sacrifice - but even death may not be enough.
