The main character/s

This book doesn't have very many characters. Somebody mentioned a few times like the characters from the Support Group.
Hazel Grace: a sixteen year old cancer patient. The narrator and main character of the book. She likes to read books, but she has a great favorite as she repeats several times, An Imperial Affliction. Sometimes it can be very annoying when she tells so much about this damn book. She has written to the author where she wants some answers to the book's ending. But she has never received a reply, which makes her sad and desperate.
I like the way Hazel tells the story and I recognize myself in some of her thoughts.

Augustus Waters: also known as Gus. A seventeen year old ex-basketball player and amputee. He had osteosarcoma, but he is now cancer free after having his leg amputated. Hazel and Gus meets in the Support Group. Hazel thinks he is very hot, and later Gus says that she is gorgeous and that he's in love with her.
They agree to read one another's favorite novels. Augustus gives Hazel The Price of Dawn, and Hazel recommends An Imperial Affliction. They both liked each others books.
Gus is a cute guy I wish all the best. He is also a little romantic. 


Isaac: is Augustus' best friend and attends in Support Group where he also meets Hazel. He has eye cancer and later in the book he loses his sight. After he lost his sight he also lost his girlfriend and he is very upset about it. He believe in true love, and try to figure out why it didn't worked out with her. He throws Augustus' basketball statues on the floor and ruins them (with Augustus permission of course, he never liked them anyway). I feel bad for him because he is such a nice guy who doesn't deserve the crap he goes through.

Peter Van Houten: the author of Hazel's favorite book, An Imperial Afflicion. He lives in Amsterdam. Hazel and Gus visit him to get the answers of their questions about the book. They are very exciting about this trip and to finally meet Van Houten, but the meeting is not as nice as they thought. When they first met him he was a selfish drunk. But by the end he changes his life and he isn't a bad person after all.
