A very solid 8/10 from me. I have to laugh at myself; it's so easy to accept strange made up words when reading fantasy, that when you're faced with real words from other languages, it throws you for a loop. Especially if you speak a little of them. I kept expecting to see hiragana or something on the page.
Anywho, that's a ramble. I loved the blend of different Asian cultures in this book. It's brilliant. I can't wait to read more of this world and see how it's developed and what's been done with it.
I'm writing on my phone, so won't talk for long. I'd recommend this book for fans of Jane Fonda's The Green Bone Saga for the blend of old and new, Will Wights Cradle and the other power fantasy stories for the adrenaline action scenes, and KS Villoso's works for the perspective of older characters.
And potentially fans of Jackson Bennetts The Divine Cities. They don't feel much the same, but thematically they share a bit.
