At the end of The Fault In Our Stars, Augustus Walters has died. Hazel is lost and doesn't know what to do without her best friend and lover. Hazel then reads a letter Augustus wrote to Van Houten before he passed away. In the letter, Augustus ask Van Houten, the author of a book they both loved and that had no ending, to write an ending for Hazel. Augustus talks about how when Hazel was dieing and unconscious, he visited her in the hospital room and wouldn't leave. He talks about how he wants to be remembered but the marks people make are often scars. The book ends with the last sentence of the letter. She had to speak at his funeral and it was very hard for her. Someone she cared about was gone.
