'It is eight years since Xuan Wu, God of the Northern Heavens, living in Hong Kong as wealthy businessman John Chen, was exiled from the mortal realm. Emma and Simone, John's daughter, are facing a new series of threats, while their best fighter, Leo, sits in Hell. They must persuade him to come home ... but, in Hell, nothing is as it appears.
On Earth, Simon Wong, the Demon King's son, is no longer around to trouble them, but his associates have taken over Simon's underworld activities. The otherworldly stones are being targeted and are in danger of their kind being completely destroyed.
It seems that the Demon King is the only one Emma can turn to for help ... ' (Publisher's website.)
Epigraph:
The Serpent slides through the black icy water of the Antarctic, wreathed in permanent darkness.
The Turtle hides from the weak Arctic sun beneath the ice.
They cry, but there is no answer.
