In what time period does the novel, What the Wind Knows, take place?

The novel opens and closes in 2001, but the rest of the events take place in 1921. The difference in time setting is notable in the fashion requirements, political climate, and social situation for the characters. Anne struggles to figure out the various clothing and toiletries available. There are extensive discussions about the politics of the time, including Thomas and Anne's interactions with Michael Collins, an Irish revolutionary. Anne talks about the luxury in Thomas's home, including indoor bathroom and the kitchen appliances. The time difference is also notable because of the differences in the language. When Anne wakes for the first time after being shot, she needs to use the bathroom but struggles to find the correct word, trying restroom, toilet, and loo in an effort to make Thomas understand.
