XD! Gah, where do I begin with how much I loved this book? It hits every mark of things I love when it comes to stories. 
 1. Strong female protagonist. 
 2. Disabled main character. Eon has a bad hip and leg. (Seriously, there are hardly any books that deal with characters with disabilities, much less a MAIN character whose disabled. So yeh, I jumped for joy when I read that. :D ) 
 NOTE: Just a note the word 'cripple' is used quite often in this book. Normally that irks me but I could understand why she put it in the first half of the novel. 
 3. Chinese Zodiac. 
 4. Asian AU fantasy setting 
 5. Gender politics (especially what it means to be male and/or female. Do you really need to look like a woman to be a woman, or do you really need all male 'parts' to be considered a man? ) There's also caste systems and the view of disabled people being a bad omen or 'evil'. 
 6. Dragons. (really, need I say more about this? XD ) 
 7. The world building....one word....WOW! 
 From start to finish I LOVED this book. There wasn't a character in this book that I did not like, even Lord Ido and he was a bastard. Wow, what an intense villain! D: *shudders* so creepy! 
 I will admit there were a few things that happened right towards the end that slightly annoyed me, but it wasn't enough to take away from my final score. 
 5 out of 5 stars! <3
