There be spoilers ahead. You have been warned.
I'd heard some good things about this book, so I decided to give it a try. I also knew the author was a fan of manga (and therefore presumably Japanese culture) beforehand. Cool. I adore manga too.
Thing is, the concept is interesting. The whole piece-of-earth-in-foreign-realm idea got me absorbed in the first chapter. Trying to make sense of all the new terminology, figuring out the history, politics (especially the inter-species ones) was all great.
And then everything kind of goes downhill.
I liked Tinker the most in the first few chapters when she was badass and saved Windwolf. It was refreshing to read about a genius heroine who is purportedly amazing at quantum physics. As I read on, however, I found myself being more and more detached from Tinker. To be honest, aside from the whole genius mechanic label slapped on her, I don't particularly find Tinker very different from typical heroines. There is proof that Tinker's 'legend' isn't false, we get to see her in action in her junkyard, but everything else about Tinker... I know some people liked her, and to each her own. I just couldn't personally connect with her (or understand most some of the things she did). Even with a smart heroine, the entire book (or at least the part I read, which was the first 4/5 of it) is spent with Tinker mired in her confusion, ignorance, and indecision. As if fiction needs more heroines tripping over their own feet.
Tinker wasn't the worse part of the book for me though. Oh no, it gets worse.
Can we talk about the racial tensions in this book? Because I can't unsee them. I can't just ignore it and pretend everything is awesome and my isn't this author cool for putting in references to the mystical Orient. On the most basic level, this is how the characters in this book go: If you're a good character, you have Caucasian features. If you're a bad character, you have Asian features. The 'good' mythological race, the one we and the heroine are supposed to sympathize with, is drawn from European mythology. The 'bad' mythological race, the oni, are drawn from Japanese mythology. Let's not forget that America is the 'good' human country, and all human characters, who are American, in the book are white (except for a brief mention of Chinatown and one stock 'Asian man' behind his okonomiyaki cart). And of course China is the 'bad' human country.
The mythology is weird too. The oni have distinctively Japanese names, the mythology is drawn purely from Japanese culture (aside from the Foo dogs, but an explanation for why these Chinese mythological creatures are included in Japanese mythology is given on p. 144). There was a mention of Chinese dragons too, as 'poisonous snakes'. Okay, now that we've established the mythology for the bad oni are drawn from Japanese culture, what is up with the repetitive discussion on China? How is China in any way connected to Japanese mythology? Why is there absolutely no discussion of Japan? Why the heck were the oni stranded in China? What were they doing in China, taking a jaunt on the Great Wall and snapping photos of the Forbidden Palace? I suppose I just feel there's something not quite right with all this talk on China and Japanese mythological creatures. Somehow the two are supposed to connect together, but I just don't see how. China has its own rich and vast mythology that, guess what, is distinct from Japan's. Why not draw on that instead?
The Elves are characterized in a way so that they seem distinct from the human race. They don't share human culture, or language. Their systems of governance and politics, their history... the author really fleshed this out. The oni, on the other hand, are too close to Japanese culture for my liking. Please explain to me how a race of mythological creatures that developed on a separate plane somehow develop a culture remarkably similar to Japan's (down to the kimono). Or have names that sound remarkably similar to Japanese names. You might argue it's because the oni were stuck in the human world and thus caught onto human culture. But oni are immortal, in their own private homes they shouldn't have to act human and should remember their own culture and language. Nor should they have to call themselves by Japanese names. And don't get forget they were stranded in China. Which. Isn't. Japan.
So yeah. Basically it's stereotyping one race as good, another as evil, and having some weird Oriental/Asian mash of things thrown in there (the continent of Asia is not some all-you-can-eat pile-whatever-you-want-onto-your-plate buffet). I would prefer Japanese and Chinese mythology to be represented properly and not caricatured, otherwise authors are just appropriating elements of other cultures and stuffing it in 'cause it looks cool. The whole Big Bad China-wait-no-Japan-wait-no-Japanese-Shinto-oni thing just doesn't work. That, and last time I was there America isn't just made up of white people. There really are other races that live in America. I know, I know, it's the whole please let's have diversity in your characters thing, but having one race as your good characters and another race as your bad characters does not cut it.
I'm not even going into the mess that is Tinker and Windwolf's relationship. Aside from the whole insta-love thing (especially on Windwolf's part) and Tinker's dallying around with Nathan and Windwolf (which I can understand but can't exactly respect). Oh, and the whole non-consensual turning of Tinker into an elf (am still puzzled by that part - as in why it was added in the beginning, forced on Tinker, with little to no set up, because the books I like the most actually discuss the differences between mortal and immortal, and characters put themselves through hell to gain immortality for maximum impact), and how Windwolf trapped Tinker into a marriage. That, and Tinker and Windwolf have no build up or basis for their relationship. They have little interaction with each other (hell, I understand and like Tinker's relationship with Pony more than Windwolf), and most of it featured Windwolf near death. Whoops, guess I did delve a bit into the train wreck.
To summarize: I don't think the author was intentionally racist (God, I hope not, although casting all your bad guys as Asian characters is cutting it really close). And great, the author wanted to incorporate other cultures. Just please, be careful with representation. Other cultures means they aren't exactly yours. You don't really know them as intimately, and honestly have no right to stereotype them as bad guys. Or somehow draw in one Asian country while discussing another Asian culture's mythology and throw them together.
