In my opinion, I absolutely loved this book. It was everything I loved in a good fantasy novel. It had action, magic, strong friendships, some adventure, and of course...romance. Kathleen Morgan does a wonderful job developing her characters and making the reader feel like they exist, especially Deidra. This young woman is so headstrong and so determined, yet at times it could get a little annoying, just because she was always so quick to have a sharp retort to come back with, that she sometimes wouldn't listen to the other side. The obvious attraction that Deidra and Hawkwind have for each other, though both deny it in the beginning, is so strong and passionate. I could just feel the tender emotion and love that they felt for each other. For the characters, this is a story of everlasting love that can conquer all, discovering their true identites, and with that love comes a way to heal the heart from past burdens and finally lay them to rest (you'll see what I mean if you read the book). If you love a good love story, this is the book for you!
(If you liked this book, I'd also like to recommend "Heart's Surrender" also by Kathleen Morgan. Both books are similar in that the heroine is very headstrong and speaks her mind, both are love stories, though it takes a while for the characters to admit their passion for one another, and it just kind of flows similarly as well. This book is also one of my favorites!)
If you want to read "Fire Queen", I suggest you do so when you have a lot of time, because you won't want to put it down!
