Sacrifice, the sequel to Serpentine, plunges Skybright into the terrifying underworld where demons are bred and whisks her up to the magnificent Mountain of Heavenly Peace where the gods dwell. Stone is stripped of his immortal status and told to close hell's breach, which mysteriously remains open, threatening mortals. Zhen Ni, Skybright's former mistress and friend, has been wed to the strange and brutish Master Bei, and finds herself trapped in an opulent but empty manor. When she discovers half-eaten corpses beneath the estate, she realizes that Master Bei is not all that he seems. As Skybright works to free Zhen Ni with the aid of Kai Sen and Stone, they begin to understand that what is at risk is more far-reaching then they could ever have fathomed.
