Skybright is plunged into the terrifying Underworld where demons are
bred, while Stone, stripped of his immortal status, must find a way to
close hell's breach before more mortals die. Meanwhile, Zhen Ni,
Skybright's former mistress and friend, is now wed to the strange and
brutish Master Bei, and she finds herself trapped inside an opulent but
empty manor. When she discovers half-eaten corpses beneath the estate,
Zhen Ni worries that Master Bei is not all he seems. As Skybright begins
the dangerous work of freeing Zhen Ni with the aid of Kai Sen and Stone,
nothing can prepare them for an encounter so dark that it threatens to
overtake their very beings.
