A friend of mine is blogging about her writing at The Search for Lillian Alling. She has a website too about this one particular project - the story of a woman who, in the 1920s, made up her mind to walk from New York across the continent and through British Columbia, then north to the Yukon and Alaska - in order to return to Russia.
Be sure to check out the website link at her blog. The story of Lillian has already inspired articles, books, a graphic novel, an opera, even thru-hiking.
You'll be intrigued too.
