Hazel Grace - The narrator

This book is written so that it's Hazel who is the narrator. You get insight into her thoughts and feelings and the actual story. I kind of like the way John Green has written this book.
As I mentioned earlier, she meets Augustus Waters. Augustus or Gus is an ex-basketball player and amputee. They fall in love, but Hazel doesn't feel she can take the next step because she don't want to hurt Augustus. So far in the book (page 155), they are just friends. But I don't think it will be long before they realize how in love they are and will take the next step.
