at nineteen years old, nicole c. kear's biggest concern is choosing a major--until she walks into a doctor's office in midtown manhattan and gets a life-changing diagnosis. she is going blind, courtesy of an eye disease called retinitis pigmentosa, and has only a decade or so before lights out. instead of making preparations as the doctor suggests, kear decides to carpe diem and make the most of the vision she has left. she joins circus school, tears through boyfriends, travels the world, and through all these hi-jinks, she keeps her vision loss a secret.
