Something is wrong with Claire, but she doesn't know what. Nobody does, not even her doctors. All she wants is to return to her happy and athletic teenage self. But her accumulating symptoms--chronic fatigue, pounding headaches, weight gain--hint that there's something not right inside Claire's body. Claire's high school experience becomes filled with MRIs, visits to the Mayo Clinic, and multiple surgeries to remove a brain tumor. But even in her most difficult moments battling chronic illness, Claire manages to find solace in her family, her closest friends, and her art. A deeply personal and visually arresting memoir that draws on the author's high school diaries and drawings, One in a Million is also a sophisticated portrayal of pain, depression, and fear that any teen or adult can relate to. With a sensitive preface and an author's note connecting past to present, this true story of resilience strikes a moving balance between raw honesty in the face of medical and mental trauma and the everyday musings of a teenager.
