I can't say I agree with you, though I understand where you are coming from. I think that it was clear from the subtitle of the book and from the back cover explanation that the book was about the author's own journey. I like that she told so many personal stories, because for me, it made the story more believable and flowing. Also, by sharing the success of what she achieved in the prison and then the hardships she went through after that, she gave real examples of how challenging it can be to try to live without regrets and to be who you want to be. I didn't feel that these chapters were superfluous at all, rather that they gave the story an unexpected twist for the better. I think if you go into the book with the awareness that it is a memoir of her own life and how it was transformed by those she cared for, then it is a beautiful book. In fact, it is one of the most beautiful books I've ever read. I was given a paperback copy as a gift and have just bought an online copy as well. Like I say, I can see where you are coming from. But I cannot agree that the book lost strength as a result of the final chapters. I thought it was courageous and life-changing all of the way through, but even more so at the end.
