The Hellraised are still infesting North Carolina, settling in, becoming detectives, whatever. But there are problems: God's gone on holiday, a Fallen Angel has escaped from Hell, if Rhea can't get more funding for her company her new space drive will never leave the ground, and her chief engineer Jack has a gargoyle living over his front door.
This takes a while to get going, because of the multiple plot threads, and the jokey style isn't quite as funny as it might be. But once things do start rolling, it gets fast and furious, and all the various strands come together in interesting, ironic, funny, and tragic ways. Good mind candy.
