After reading the synopsis, a co-worker of mine said this book sounded depressing. I get that - I mean the book is about teens who have cancer. But the characters lift the story above what could be a dark tale. They are trying to be regular teens who not defined by their disease. This is not always easy when they have frequent doctor visits, constant physical limitations and parents who, out of love and concern, hover over them with worried expressions and fear of what may happen to their children.
At the center of the story, we have Hazel who needs assistance to breathe because her lungs are very weak. She meets Augustus at a support group. Their growing relationship drives the story. They become closer through Hazel's favorite book that leaves her with too many unanswered questions. Contacting the author to find those answers becomes a key point for them. Through it all they deal with a disease that could turn on them at any point.
