Someone is killing half-bloods (half-elves, half-humans) in a small city. The police believe that it's nothing more than a regular maniac obsessed with racial purity. But detective Blackwood and magician Silverlight have their own opinion about this case. They think that the killer is a necromancer going after the souls of half-bloods, who wants to use them for some horrible ritual. The protagonist, a young half-blood girl called Mia Silverlight, falls into a whirlpool of events. Will she be able to avoid getting caught by the killer, find true love, and discover the secret her uncle is hiding?
