Thanks for those of you who suggested your favorite fairy tale books! (If you didn't get a chance to, add yours to the comments!) I'm excited to have your most recommended fairy tale readings and hope it's helpful for you as well!
From Sue Bursztynksi:
Kate Forsyth's Bitter Greens (Rapunzel), The Wild Girl (Dortchen Wild and the Grimms) and The Beast's Garden (The Singing Springing Lark/Beauty and the Beast in Nazi Germany)
Moonlight And Ashes (Cinderella) and Hunter's Moon (Snow White, set in the nineteenth century, in a fictional country, and the "Kingdom" is a department store chain with its own fashion label, the Mirror is a newspaper which writes articles saying that the stepdaughter is the new "Fairest") .
Mythic Resonance. It's only available in ebook now, but you can get it. It has various stories based on mythological or fairy tale themes. (Mine is Snow White, with Tolkienesque-type dwarves who are more likely to get out their axes and defend her than sniffle over a glass coffin!)
Also, anything published by Christmas Press, an Australian small press run by Sophie Masson and some artist friends. They publish picture storybooks for children, each with two folktales or myths from a different country, retold by a well known children's writer, and beautifully illustrated. Actually, mouth-wateringly illustrated! They're available on line.
From Adam Hoffman (Fairy Tale Fandom):
The Lunar Chronicles (Cinder, Scarlet, Cress, Winter) which is a series that does a sci-fi take on four different fairy tales (Cinderella, Little Red Riding Hood, Rapunzel, Snow White) as an interconnected story.
A Kiss in Time by Alex Flinn which is "Sleeping Beauty" recast as a teen rom-com in which the princess is awakened three hundred years later by an American teenager who ditched his tour group.
An Earthly Knight by Janet McNaughton which is a teen fantasy retelling of "The Ballad of Tam Lin".
The Sisters Grimm by Michael Buckley, which is a modern-day fairy tale mash-up in the same mold as Once Upon a Time or Fables but which I just think has a lot more fun with the premise.
Beauty, although I feel like I mention it all the time!
Red as Blood and the series edited by Ellen Datlow and Terri Windling were really influential for me
Black Swan-a retelling of Swan Lake from the perspective of Odile, the magician's daughter (NOT related to the Natalie Portman movie)
Mirror Mirror-In a completely different vein, a children's book-I've also mentioned this several times, but the concept of poetry that can be reversed still fascinates me, and each poem is amazingly able to show two different perspectives of a fairy tale. There's also a sequel, Follow Follow, which I don't own
