At the age of thirty-six, on the verge of completing a decade's worth of training as a neurosurgeon, Paul Kalanithi was diagnosed with stage IV lung cancer. One day he was a doctor making a living treating the dying, and the next he was a patient struggling to live. Just like that, the future he and his wife had imagined evaporated. When Breath Becomes Air, which features a Foreword by Dr. Abraham Verghese and an Epilogue by Kalanithi's wife, Lucy, chronicles Kalanithi's transformation from a naïve medical student 'possessed, ' as he wrote, 'by the question of what, given that all organisms die, makes a virtuous and meaningful life' into a young neurosurgeon at Stanford, guiding patients toward a deeper understanding of death and illness, and finally into a patient and a new father to a baby girl, confronting his own mortality.
