PROBLEM: Review: I'm glad that L. J. Smith finally put a witch book in her series. I love vampires but it wouldn't really be good if that's all she wrote about in the Night World series. Now she needs to put in a shapeshifter novel and she'll be on a roll. The only thing I don't get about the book is why Thea got expelled with Blaise when she didn't do anything. I hope she became a famous vet. 
 Polarity: Negative

SOLUTION: False

PROBLEM: Review: This book is terrible. The writing is terrible, the art is terrible (obviously terrible, too: one of the dragons' heads was obviously photoshopped onto another dragon's body on another page), the story is boring, it's just... bad. It's anti climatic, and throughout the story it's just hardship after hardship of them attempting to kill dragons. I found it hard to finish just skimming it.
