According to author John Green, The Fault In Our Stars was inspired by his friendship with Esther Earl, who "redefined the process of dying young for me." (December 2012 Good Reads interview, http://www.goodreads.com/interviews/show/828.John_Green). He cautions his readers not to take the novel too literally however, stating that he doesn't "want people conflating Esther with Hazel (they're very different), and it's extremely important to me that I not claim to be telling Esther's story. Esther's story belongs to Esther and to her family." (John Green's tumblr, August 2, 2012 http://fishingboatproceeds.tumblr.com/post/28557373623/everybody-was-told-to-make-a-funny-face-but-i). Esther's story is told in the 2014 posthumous memoir This Star Won't Go Out : the Life and Words of Esther Grace Earl.
