From Wikipedia:

Hazel Grace Lancaster

Hazel Grace Lancaster, 16, is the novel's narrator. She goes by Hazel, but Augustus (and sometimes his father) calls her "Hazel Grace". She is a thyroid cancer patient, having been diagnosed when she was 13. She is an only child, and fears what will happen to her parents' relationship after she dies. She is on a "miracle" drug that will lengthen her life by an indeterminable amount of time. She meets Augustus at a support group but does not initially want to pursue a relationship with him, as she wants to minimize the hurt that her death will cause. She has few friends, and prefers the company of books, particularly the fictional An Imperial Affliction, by Peter van Houten. Green stated in a vlog that he named her Hazel "because it's an in-between color, and she has an in-between life, in-between health and sickness."

Shailene Woodley will play Hazel Grace in the movie adaptation of The Fault in Our Stars.

Augustus Waters

Augustus Waters, 17, is in remission. He was diagnosed with osteosarcoma at a young age and lost his right leg to the disease. He loves video games, in particular Counterinsurgence 2: The Price of Dawn and the novel versions of the game. He is initially intrigued by Hazel because of the physical similarities between her and his late girlfriend Caroline Mathers. Augustus uses his Wish (given to him by the Genies, a fictional version of the Make-A-Wish Foundation,) to take himself, Hazel, and her mother to Amsterdam to meet Peter van Houten.

Ansel Elgort will portray the role of Gus in The Fault in Our Stars movie.


Isaac, Augustus' best friend. He has eye cancer, and eventually loses his sight because of it. In the beginning of the novel, he is dating a girl named Monica, who dumps him shortly before Isaac goes blind. Isaac is devastated by this, and finds support in Augustus and Hazel.

Isaac will be played by Nat Wolff in the movie adaptation of The Fault in Our Stars.

Peter Van Houten

Peter Van Houten, a recluse author whose first and only work, An Imperial Affliction, serves as the basis of most of Hazel's beliefs for both her life and relationship with Augustus. Peter has become a drunkard, and refuses to provide Hazel and Augustus with the answers they seek about his book unless they come to Amsterdam. He is obsessed with Swedish hip-hop group Afasi och Filthy.

Mrs. Lancaster

Mrs. Lancaster, Hazel's mom. She often takes every opportunity to be enthusiastic at small occasions, such as Hazel's "half-birthdays", and Bastille Day, a French holiday. Hazel describes her mother as her best friend.
