No, she actually writes about that in the book. Her second walk across the US was to make amends.
I thought she came across as someone who, after an almost impossible childhood, some flirtation with drugs at one point and with more hang-ups than most of us ever have to cope with, had come to terms with herself at last. Even early on, she was remarkably observant and perceptive. I thought the book was very honest and it cannot have been easy to write.
