I knew from the first time I saw the epic cover that I would enjoy this story - and Riven Earth did not disappoint. The action-packed prologue had me instantly intrigued and provided a fascinating insight into Astea. The world building felt very unique with its rich history and interesting flora & fauna, and unlike anything I've come across so far. Add to that a diverse cast of morally grey characters and my interest is more than piqued.

Ahmer shines with his characterizations of flawed and multi-layered people, all struggling with things from the past that haunt them, trying to find a way forward - for better or worse. I especially liked Raia and Kaido (though I hope to see more development with Kaido's character in book 2), but Otto (in an unexpected turn of events) ended up being my favorite. I found myself looking forward to his chapters, feeling & rooting for him - which I would not have guessed from the very start. He actually reminded me a bit of Abercrombie's characters, giving me strong Sand dan Glokta vibes, and sending me on a similar journey of "no way I'm gonna like him" to arrive at "damn, I can't not like him". ^^

In Riven Earth, Ahmer explores an array of themes, such as religion, zealotry, racism, corruption, environmental destruction, and climate issues, but also touches on mental health, grief, depression, and suicidal ideation. All these topics are seamlessly incorporated into the plot and give the world and its characters a lot of depth and tangibility.

Riven Earth is a very strong debut and a great start to The Book of Astea duology that sets up (what I believe will be) an exciting conclusion in Sundered Moon. I have already purchased book 2 and can't wait to get to it!

*Thanks again to the author for providing me with the audiobook in exchange for an honest review. I'd already had the e-book waiting on my Kindle, so I used the audio to immersion read.
