My opinion: 
 as in general the book was very good and action packed and all the characters were interesting and perfect except Dalilah Bard...I didn't like her AT ALL!So selfish and reckless through all of the book. 
 I didn't like the way she looked at Kell like he is only a piece in her games while he still have feelings for her. 
 I hope the 3rd book will be better than this one.
