No. No no no no no. What is it with white authors inserting phonetic Japanese into their stories for """authenticity""". It didn't work for me when Stormdancer did it and it doesn't work here either. 
 I just. No. It's too reminiscent of being fourteen and writing terrible fanfiction. Which, incidentally, is the only demographic I would recommend this book to. If you're a teenager who has just discovered watching anime with the subtitles on, you'll probably love this. Otherwise, definitely give it a pass. 
 It's just a rehashed version of every other paranormal romance book in the history of existence. The Japanese setting is the only unique bit and even though I believe Sun knows what she's talking about from a well researched perspective, you can't tell me there are no actual Japanese authors who aren't trying to do this. 
 And I'm sorry, mysteriously our white girl protagonist has an inexplicable link to Japanese lore? No. Just. Why this? I saw someone else mention in their review that it would've made way more sense for Katie to be Japanese-American and yes. That's exactly it. 
 And that's really only the beginning of the super-problematic elements of this book. But I'll spare you the rest of the details. Seriously, don't bother.
