The "West of the Sun" is the title of chapter 35 of Educated (Tara Westover' book).
I searched the web to find meaning of the title and I found the explanation below:
"West of the Sun", meaning taking a step beyond reason, and in doing so risking everything to obey powerful.1
Is it a right explanation of the phrase? Is there any other meaning for the "West of the Sun"?
Note: South of the Border, West of the Sun is a short novel by Japanese author Haruki Murakami.3 South of the Border is a song about Mexico. But what is west of the sun? Shimamoto called it hysteria Siberia and told one story: "Try to imagine this, you’re a farmer, living all alone on the Siberian tundra. Day after day you plow your fields. As far as the eye can see, nothing. To the north, the horizon, to the east, the horizon, to the south, to the west, more of the same. Every morning, when the sun rises in the east, you go out to work in your fields. When it’s directly overhead, you take a break for lunch. When it sinks in the west, you go home to sleep. In the winter they stay home and do indoor work. When spring comes, they head out to the fields again. Anyway, that cycle continues, year after year, and then one day, something inside you dies. Maybe nothing or maybe something in the west of the sun. At any rate, it’s different from south of the border.” 3
