Of Earth and Air is an upper YA dark fantasy book and the third installment from the Heir of Blood and Fire series. Digging into this book was quite immersive, interesting, and exciting. It was swoon-worthy, action-packed, and compelling. The whole premise was just very entertaining and full of many things that you wouldn't expect from a book. I honestly enjoyed it ever since I started reading the first installment to the third one. It was fun, the writing was impressive as well as the plot. The plot will leave you giddy, excited, and hanging (cliffhanger). I finished it in one sitting because you couldn't put it down. The character's chemistry was great. Calla and Trystan's relationship was just solid, angsty, and raw. However, I've said from the other books that my connection towards the characters and even from the side characters of this series was still in the process of embracing them, I still couldn't feel anything from them even now in the third book. I'm still in that process, and it's very disappointing on my part. Overall, this book was a ride and worth reading. I just hope revisions will make this book even better, and I expect more from the last installment of the series. Please, no more cliffhangers, and give us the happy ending we deserve. Ps. I just want to point on something I find so funny and ridiculous from the book: "Brynna was fine with it because she loved to travel, and Sabine was giddy to just experiencing the world outside of Morbeth. Thalia was so relaxed about everything." I personally find it so funny and ridiculous when I've read that (but there are few of them) and I'm so sorry to point this out despite the fact that I was reading the ARC version of this book. My point is, you're not supposed to say that when you are in pursuit or in hiding from your enemy. Your life and your friend's life was in danger and you have the guts to make it as a fun adventure. Nevertheless, it was still a great book. Rating: 3.5 stars/5 stars
