I was blessed with an ARC of this precious, and not gonna lie, I went in expecting one thing and got something completely different. Not BAD different, just different. I went in expecting your stereotypical hot dragon shifter and peasant girl chosen one romance story. That, my friends, is barely the tip of the iceberg.
Blood Oath follows Ryn a peasant from the outer provinces under a rule of a ruthless king who has led his people to intolerable starvation. The King's Drae (read: dragon), Irrik is known for following the king's orders with ruthlessness and precision, under an oath that bound him to the king's will many years ago. When Ryn gets mixed up with Drae and mistaken as a rebel, her life is over- or it would be if Irrik hadn't noticed something about Ryn that made him pause and defy the cruel system he has helped enforce.
If you're looking for the aforementioned plots, you must read Blood Oath! Ryn is a strong character but can, albeit, be a bit lackluster and naïve for someone going through her specific scenario. She sets her emotions first and brain last which was a bit frustrating. The only other comment I'd like to make is that this series desperately needs at least one other POV, I can totally see why the authors weren't able to in this first book, but going forward I'd love to get Irrik's POV.
