I love to read and can get very attached to my opinions, but recently I've been learning not to completely lose my head when people disagree with me, so feel safe to argue with me whenever you wish ;)
Gender flipped Snow White:
Evil stepmother queen-->evil stepfather king
Beautiful princess with black hair/pale skin-->handsome prince with black hair/pale skin
Seven dwarves-->seven sisters, one of whom is the love interest and protagonist.
I wish I've read more Snow White retellings besides the original fairy tale the Disney movie to compare this to, but I have not, except for Fairest which doesn't count as a traditionally faithful retelling for me.
The magic reminded me a lot of Uprooted, sinister and dark on one hand, wondrous and beautiful on the other. One difference would be the amount of exposition. Huchton doesn't explain much, and I liked being forced to intuit the workings of the world for myself. Another would be that the main character, along with her siblings, also has a specialized inborn skill. I would guess that this is the equivalent of the seven dwarves each having an individual trade.
Characterization, especially the romance, was weakest part of the book. Maybe I'm being too sensitive, but there were a few too many times of this:
"That is a person with a truly lovely spirit. You are filled with beautiful things, Raelynn."
Blah...kind of ruins the magic, if you ask me. The non-Snow White retellings I've read tended to have decently developed relationships, so I know it's not impossible.
But this succeeded in pulling me along quickly and creeping me out on the moments it needed to. Occasionally unrealistic dialogue detracted from the sense of wonder just a little.
