I highly recommend Tales of a Female Nomad by Rita Golden Gelman and A Year By The Sea by Joan Anderson. Both of these gals are the real deal.
Rita's book is an account of her life as a nomad for the past 16 years. In her mid 40's she divorced, sold her home & furnishings and bought a plane ticket. She hasn't stopped traveling yet. I had the good fortune to meet Rita Golden as she passed thru my town and she cooks great Thai food.
If you are looking for fiction - anything by Laurell K. Hamilton. I liked Obsidian Butterfly. All of her women are strong and sassy.
