I'm on my way back after taking a few days off for the holiday weekend. To start off, this is mostly off topic, but Amazon just created a Sunshine Deals list of bargain Kindle books ranging from $.99 to $2.99 with many interesting titles. There is a Georgette Heyer I already owned, The Grand Sophy, for $1.99. I haven't had a chance to look at all of the titles yet, but if I find any more fairy tale specific ones, I will share. There is every subject and genre represented but since this is SurLaLune, I will focus on the fantasy.
Here are some I found with a quick look:
Dreaming Anastasia is $1.99 and that one does have some Baba Yaga in it.
Entice by Carrie Jones has pixies and Valhalla.
Philippa Fisher's Fairy Godsister is $1.99
The Tail of Emily Windsnap is $1.99 and is obviously about mermaids.
