Victorian Secrets: What a Corset Taught Me about the Past, the Present, and Myself by Sarah A. Chrisman http://www.amazon.com/dp/1626361754/ref=cm_sw_r_pi_dp_We8Yvb1T45D99
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
