"It's been four months since the night of gore, chaos, and the failed demonic summoning that revealed the Ting twins' unusual family background. Since then, Milly and Billy have tried to explore their new powers, but their parents, Ipo and Keon, haven't been much help. Despite the lack of explanations, one thing is abundantly clear: the Ting family is part of a much larger supernatural world and something in that world is very, very wrong. As Ipo and Keon are reluctantly drawn back into the treacherous high society of supernatural elites, their children find that dealings with the spirit world comes at a steep price-when the dead have unfinished business with the living, only blood can balance the scales. To save humanity and themselves, the Tings will have to embrace their inner demons"--,Provided by publisher.
