When told she has a year to live she leaves the control behind to live her remaining bit of life.
The plot may sound fanciful but it is grounded by Montgomery's realistic (at time of writing) description of the cowering Valency and her stuffed shirt relatives.
The book kept me hoping in second chances for twenty-nine year old spinsters :)
When cousin Stickles knocked at her door, Valancy knew it was half-past seven and she must get up. As long as she could remember, Cousin Stickles had knocked at her door at half-past seven. Cousin Stickles and Mrs. Frederick Stirling had been up since seven, but Valancy was allowed to lie abed half an hour longer because of a family tradition that she was delicate. Valancy got up, though she hated getting up more this morning than ever she had before. What was there to get up for? Another dreary day like all the days that had preceded it, full of meaningless little tasks, joyless and unimportant, that benefited nobody. But if she did not get up at once she would not be ready for breakfast at eight o'clock. Hard and fast times for meals were the rule in Mrs. Stirling's household. Breakfast at eight, dinner at one, supper at six, year in and year out. No excuses for being late were ever tolerated. So up Valancy got, shivering.
