3.5 stars. 
 Ooook, I struggled to finish this book :( I don't know what happened!???? Except for one thing or another AND the last chapters (view spoiler)[(from the moment that Aelin went to destroy the towers to the last page *TRULY AWESOME*) (hide spoiler)] this book was pretty boring for the most part. Heir of Fire is still the best (and my favorite one) book in the series. PS: the secondary characters in this series are so amazing!!!
