Missing fourth wing? Want something without dragons? Something similar but with MM romance? Then this story is for YOU! Greylith quickly had me hooked, and of course left me on a bit of a cliffhanger wanting more. This is a much faster paced fantasy with MM romance, unique magic, and unlikely friends. Plenty of traitors to. But who's a friend and who's a foe? Read this to find out! I know i loved being caught up in the rush and honestly kinda wanna be a part of the group.

Greylith is the kind of fantasy that grabs your attention from page one and keeps hold of you until the last chapter! (Brace yourself!! It ends in a cliffhanger!) This book is packed with action, a UNIQUE magic system, found family, and a love interest! 👀❤️

The magic here isn’t just flashy- it has weight, consequences, and rules that make it feel real. Watching the characters learn, bend, and sometimes break those rules is half the thrill.

If you’re a reader who craves:
📜 A magic system you’ve never quite seen before
⚔️ High-intensity action scenes
🌍 A world that feels ancient and lived-in
💔 Emotional stakes as high as the physical ones

…then Greylith deserves a spot at the top of your TBR. 📚

ARC reader here. All opinions are my own.

I had the absolute pleasure of Arc reading Greylith.

If you are looking for a fast paced fantasy with a unique magic system and a sprinkle of spice - this is for you. This is book 1 of a planned 6 book series and you will fly through this book once you start. You will need to know EVERYTHING that happens next.

If you happened to have read the original, I’m telling you this rerelease is worth it!

Greylith by F.A. Seng completely hooked me from the first chapter. It’s fast-paced with a refreshingly unique magic system that feels both powerful and emotional. The MM romantasy between Phoenix and Xander is beautifully written slow burning, intense, and genuinely heartfelt. I also loved Phoenix’s bond with his sister and friends their dynamics felt real and added so much depth. The story is packed with action, emotion, and magic, but never loses sight of its characters. If you’re into romantasy with strong relationships, high stakes, and a world you can disappear into, this is a must-read. I need the sequel now!

If you like fantasy romance with a unique magic system, slow burn, found family, and incredibly high stakes, you should read Greylith by F.A. Seng. Our MMC Phoenix Greylith finds himself reluctantly recruited at Fort Weave and training for a brewing war. He learns he has a very powerful and feared form of weaving magic and struggles with learning it, controlling it, and not being consumed by it - all while navigating relationships with his sister, his fellow recruits and his mentor Xander Nightingale. The magic system here is so interesting and the world is introduced in a way that isn't overwhelming, but leaves me excited for more from Phoenix and Aetheria.

Thank you to F.A. Seng for an ARC of Greylith. I enjoyed reading this so much and look forward to more stories from Seng. All thoughts expressed in this review are my own.
