The fault in our stars

Hazel Grace is 17 years old and has been living with cancer for three years. Even though she is a girl with an active mind. Her cancer began as thyroid cancer but spread to her lungs, that´s why she need to breathe oxygen from a tank through the whole day. She take part in a support group at a church. There she meets a friend name Isaac and his friend Augustus. After Augustus lost his leg he has been improved. Then Hazel Hesitates in starting a relationship with him, not wanting to hurt him. She introduces Augustus to her favorite book, and he makes a plan, where they will travel to Amsterdam together (using the "Wish" given to him by a foundation for children with cancer) to meet the author and find out what happens after the book's end. They are able to take this trip, but when they arrive to meet the author he is drunk and grumpy. At the end of the trip, Augustus says to Hazel that his cancer has come back and is much worse than the previous time. They return home and Hazel stays by his side until his death. The author attends Augustus's funeral and tries to apologize to Hazel. She realizes that his book, which is about a young girl with cancer, was based on his daughter who died. Hazel is dealing with Augustus's death, and she is cheering up herself with the letter about her that Augustus sent to the author before his death.
