Currently, I'm reading Cattle Lords and Clansmen by Nerys Patterson as research for a novel that has an early Celtic society. But I've also been considering what faerytale standalones might come from some of the more obscure faerytales, so I've been collecting Andrew Lang's collection of "fairy books." I have a copy of the Blue Fairy Book, and the Yellow, Pink, Grey, and Crimson. But I still need all the others: the Red, Green, Lilac, Olive, Brown, etc. I found the Pink and Crimson at a used bookstore, and I'm hoping that eventually I'll luck out and find the others used as well. Even for Dover, they've gone up a lot from their starting price.
