You can read all about Billie in Ms. Bradley's book, and summaries of her life can be found here. Born in the wild in India in 1962, Billie was brought to the Southwick Zoo in Mendon, Massachusetts, in 1966. In 1972 she was sold to the circus industry and endured a life of egregious abuse until she became the twenty-first resident of The Elephant Sanctuary in Hohenwald, Tennessee, in 2006, after living for 13 years in a tiny stall in a Hawthorn Corporation barn in Illinois because she was declared dangerous.
Billie's recovery is truly miraculous. Of course, it wasn't easy, and "Last Chain on Billie" provides all of the gory and heart-warming details. After years of rehabilitation, Billie still is occasionally angry, but who wouldn't be after being unrelentingly tortured for years? I know most readers want to know why Ms. Bradley's book is titled as it is, but I don't want to ruin the story so I'm not going to tell you why. It's easy enough to find out in any number of places. However, I strongly encourage you to read the book until the very last sentence.
