A paranormal firebug is terrorizing St. Louis and as the paranormal expert Anita Black get to help the police and the fire department to track down the culprit. 
 The story line is somewhat convoluted, which takes a star from the rating. 
 Her involvement with the master of the city is growing more intense and complex, without any real explanation. 
 A good read, but there are a lot better books out there.
