The Blood Binding

Belladonna Johnson is getting used to being the Spellbinder-saving the world, seeing ghosts, and taking regular trips to the Land of the Dead have become positively humdrum. But when she and Steve discover a girl who has been waiting two thousand years for someone to rescue her, they find themselves involved with Old Magic and people and spirits unknown to even the mighty Queen of the Abyss. This time they are on their own, and to make things even more complicated, it's Halloween, the one time of year when ghosts can go wherever they want, which means it's even more difficult for Belladonna to work out exactly who is alive...and who is dead.
