What is a summary of Jump at the Sun: Zora Neale Hurston's Cosmic Comedy?

Jump at the Sun: Zora Neale Hurston’s Cosmic Comedy is John Lowe’s scholarly analysis of Hurston’s work that focuses on its comedic aspects. Lowe argues that the elements of humor that Hurston uses to deal with serious subjects have contributed to her work’s long-lasting success. Realizing the important place of humor in navigating the difficult circumstances of African American life, Hurston both incorporated comedy into her writings and wrote about its role in African-American society. The “cosmic” aspect of Lowe’s title refers to the religious traditions from which Hurston drew, showing African influences on African-American belief systems.
In the book’s chapters, following an introduction that traces the path of developing her comic voice, Lowe analyzes some of Hurston’s key works, concentrating on Jonah’s Gourd Vine; Their Eyes Were Watching God; Moses, Man of the Mountain; and Seraph on the Suwanee.
