This book is a great follow-up to Dead Witch Walking. Harrison has really matured as an author. Her heroine Rachel is back along with Jenks the pixie and Ivy the living vampire (vampires are a race in this alternate reality) and a few other characters from before like Trent. 
 In the same vein as the first book, the setting is in the Hollows, a section of future Cincinnati where supernatural creatures have come to haunt. The story takes place about a month after the conclusion of the first book, as Rachel takes on a new case: finding Dan, a missing warlock. Since the authorities require a 72-hour waiting period she gets the chance to jump in first and, perhaps, earn some much-needed cash. Pretty soon the inevitable bodies start piling up, in this case ley line witches (those who gain their power via the ley lines they tap). To make matters worse, Rachel finds herself chasing a serial killer who feeds on practitioners of the most powerful form of black magic. And she failed the ley line witch class she took in college, a bit of a disadvantage... 
 This book is fun, witty, and better than its predecessor. I enjoyed it a lot.
