Hazel Lancaster's mom thinks she's depressed. And Hazel agrees. But as far as the 16-year-old sees it, her depression is a mere side effect of dying from the stage IV cancer she's been battling for years. Still, Hazel's worried parents believe that if their daughter joins a support group, her depression will lift. She'll socialize, make new friends, and share her experiences with kids who know exactly what she's feeling. Turns out, Hazel's parents are right. Hazel's mood elevates the minute she meets Augustus Waters, a hot 17-year-old with "a touch of osteosarcoma" (bone cancer). Their connection is immediate. They get each other. Augustus even understands Hazel's need to meet the author of her favorite book, a beautiful story about life and death with a maddeningly ambiguous ending. Can Augustus help Hazel find answers and meaning before it's too late? Despite its serious subject matter, this well-narrated work offers a hopeful message about love, faith, and renewal.
