what was his purpose?
John Green was a chaplain at a children's hospital surrounded by children with life-threatening illnesses for five months. That was what inspired him to write The Fault in Our Stars. He was also inspired to write it because of the death of his friend Esther, who died from cancer. In the book, John Green gave the main character, Hazel, the same type of cancer Esther had. Those two things are what gave him the ideas to write the book. It also helped him, knowing Esther and the children in the hospital, they helped him learn about the life of a child with cancer better. He also wanted to write the book because he feels that cancer is something that isn't understood. There were a lot of things that inspired him to write it, and then he just put that all into a story, so that young people can get a glimpse into the lives of two sick teenagers in love.
