It reminds me a lot of "The Way of Kings" in that the main character is an underdog from a lower "class", who strives to become as strong as the warrior nobles (a feat considered impossible).
However, unlike TWOK it only follows one character's perspective, and he spends all his time surrounded by dudes as they train together and fight against each other. Even though their society is supposed to be matriarchal, the only evidence of that is that people take their mother's surname. Beyond that I'm not really seeing anything different and would've liked the author to explore that aspect a bit more.
I think I did feel a bit disappointed that although the women have strength (they can summon dragons) they still need to be protected by the men, and the main female characters only seem to exist as potential love interests. I've probably been spoiled by the Priory of the Orange Tree!
Nonetheless it was still an enjoyable read though, would recommend for fantasy lovers.
