"Heroine dresses like a boy" is pretty much a guaranteed way to get me to read a book. Not a guarantee I'll love it, though. I found the dialect a little overbearing and distracting and the plot a little thin, but mostly, I just didn't connect with any of the main characters, which is becoming a trend for me and YA. The character I liked the most was Liluye, but she didn't have much to do beyond get saved by the protagonist and then serve as her mystical guide. I liked the historical setting and the fact that a woman sets out for revenge, but the end product was far from a home run for me.
