At only 36 years old, Dr. Kalanithi was diagnosed with terminal lung cancer. Suddenly, he found himself thrust from the role of a neurosurgeon to that of a dying patient. Coming face-to-face with his mortality, Kalanithi decided to write his memoir and wrestle with the question: "What makes life worth living in the face of dying?" Easily one of the best memoirs of recent years, When Breath Becomes Air is a look at the heartbreaking decisions Kalanithi faced as he contemplated a life without a future.
