I was somewhat disappointed to find that 75% of the book's content was made up of letters Johnny wrote to Vivian before their divorce, mostly while they were happily married. Overall it was very interesting and enlightening getting Vivian's perspective and experience in her life with Johnny Cash. Ironically, the read helped me understand both sides much more. Vivian was very much in love with Johnny and because she just couldn't move on after the split, she had a really difficult time and much pain in her latter part of her life. Very sad. It's obvious she was a good soul but I think Cash needed something more in his partner - not sure what exactly...more dynamic, sophisticated or intelligent...maybe one of those. He seemed to find that in June Carter, who I'd always had a high opinion of until reading this book.
