Emma teeters on the edge of becoming fully demon and must make a journey to the Kunlun Mountains in the West, home of the reclusive ancient goddess Nu Wa, in an attempt to regain her humanity.

Travelling with Emma is Xuan Wu's daughter, Simone, who is struggling with her growing powers and trying to defend herself from the demons who want to destroy her.

And Michael is trying to come to terms with the shock of finding out he might be half demon ... and a danger to them all.
