The Kindle edition of Jay Kristoff’s “Stormdancer” is currently on sale via Amazon.com, for $3.34 Canadian. Not sure if Americans get a similar good deal (though probably they do).
I haven’t read this one myself yet. On one hand, it sounds like it could be interesting, and it’s gathered some good reviews. On the other hand, I’ve seen proof that it plays fast and loose with not only Japanese culture, but also the Japanese language, and the examples I’ve seen have made me wince. But still, to each their own, and if you want to give this book a try, now’s the time to go for it, while the price is low!
