The 1891 'Celtic Fairy Tales' by Joseph Jacobs is an anthology that includes "Munachar and Manachar", the "Brewery of Eggshells", and "Fair, Brown and Trembling".
Based on the true story of Genie (Katie, in the movie) who was kept strapped to a potty-chair and locked inside a cage by her father. I learned about her in Psychology class and developed an interest in Feral Children.
No, I haven't read the book. But I fully intend to read "Life of Pi" before the movie comes out. The production value and casting sound interesting and of course the story alone sounds fascinating. I might just give it a try. At least it looks good
