First off, I've read yaoi for a long time. I've collected it, attempted to translate it, gave up translating it, and mispronounced it for quite a few years now. My collection is modest but acceptable. But this is not yaoi.
This is a cry for help.
I'll get the good parts out of the way, first. The fashions are exquisit, with tassles, fasteners and seam lines creating a fantastic wardrobe that has weight to it. It looks real despite being fantasy, and I can see real people wearing these clothes. And so ends to good part.
Had I known the book would have read like a bad fanfic wrapped up in an emo song, I would have passed. The characters were So Traumatized. They had Such Horrible Things Happen to Them. Most of these things were added for shock value, and add no credibility to the story. Also, while not drawn or spoken of for greath lengths, shota plays a part. I'm sorry, I'm a lot of things, but not a shota fan.
The characters are all stock. The reactions are nonsensible. I don't expect a lot of realism from my fantasy, but some logic adds that kernal of truth that allows disbelief. "Oh, hey, you killed my evil step-dad and kidnapped me to a place where you'l kill me but it's OK because you love me." That's not love, that's the Stockholm Syndrome.
All in all I'd pass. Flip through it for the outfit Davon wears when fetching Aeon, or any of Moors' outfits. Wonder in the art that is the scenery; the archetexture and backgrounds are truely lovely. But you don't have to stay for incest, repeated sex scenes, and illogical actions.
