Definitely the best in the series so far! I can't wait for the next one! 
 My observations - not really a review 
 - While the first 3 books were urban fantasy this one is more like a classic fantasy book. 
 - I adore that Caria keeps saving her self! 
 - The sex scenes in this installments are much better 
 - Beautifully done storytelling and a great handling of a really nasty scene. Never letting it become excotic or sexy but letting it be wholly wrong and terrible without being horrible and unbearable for the reader.
