When I was a kid I was a fairy tale addict. I remember that over the course of a year, I read every fairy tale book in the main branch of the Chicago library. Every two weeks I left with as many books as I could carry! My favorites were the Andrew Lang series of collected world fairy tales, with each book arbitrarily titled by a different "color". As I read I felt transported by these tales to magical exotic realms and mystical times.
The most memorable fairy tales for me though were the Russian tales of the witch Baba Yaga. What horrible nightmares they gave me -- but I was truly hooked!! Fairy tales quickly transitioned me to a lifelong love of science fiction, fantasy, and horror literature.
