I'm a sucker for basically anything pitched as "[story you know], but with lesbians." Still, I'm usually skeptical of Cinderella retellings--how many more ways can Cinderella be retold? But this book has an enchanting (pun intended) mix of the scary sort of fairy tales, the warm and fuzzy sort of fairy tales, and tension between the real and fairy worlds that makes it feel genuinely unique. I adored Kaisa as a character, and the romantic tension between her and Ash was woven as elegantly as a medieval tapestry. That, plus the casual inclusion of other queer women in the storytelling, made this a favorite among the many, many fairy tale retellings I've read over the years.
