I was browsing and found a brief summary of the series:
"The Ninth Widow tells a story of a woman villager Wang Putao from an isolated part of Central China who loses her family in early childhood in a flood disaster. She is bought as a servant and widowed at age 14. Wang hides a fugitive man in her cellar and cares for him for the next 30 years, through political campaigns, famines, and various man-made disasters."
And from a review of someone that read the actual book, she stated it was pretty good and entertaining. According to her (the reader):
"Putao is a genuine spirit, pure of heart, dewy eyed, with an outspoken morality and even a sense of humor."
