John Green is a contemporary author of several young adult novels. His works are usually set around the time they are published and deal with issues facing his teenage audience. Like many of his other novels, John Green sets Turtles all the Way Down in modern day. Published in 2017, the work of fiction takes place in the 21st Century in Indianapolis, Indiana. The work's main character, Aza Holmes, lives in a suburb of the city.
Because the work is contemporary, audiences will be familiar with many of the restaurants, events, and references discussed in the text; for example, the characters discuss the White River, which is a real river that flows through downtown Indianapolis. However, because it is a work of fiction, many aspects of the book, like the name of the high school (White River High School) is made up.
