While I'm on the subject of great travel books, Rita Golden Gelman's Tales of a Female Nomad, was a book I read some 5 years ago.
It tells the story of Gelman, who, despite having lived a privileged existance, felt trapped in an unhappy marriage. She courageously decided to follow her dream and take off to see the world by herself. Little did she know far she would travel, or that she would continue to be travelling some 20 years later.
Gelman's inspiring journey through places like Mexico, Guatemala, Israel, Indonesia, and the US provides close-up glimpses of everyday life in other cultures, while inspiring readers to question their notions of "freedom" and the fear that most often holds them back from being "free".
