She probably does die, after Gus' death. It had a big impact on her and she was already at stage IV cancer. But I do like how John just left it there for our imagination, so we don't have to feel the pain of Hazel's death too.

But that part is still unknown and John made no sign of continuing any unanswered questions in the book.
