This account by the well known Indian/American blind writer describes experiences when he came to the United States at age 15 from New Delhi to attend the Arkansas School for the Blind. The title derives from an unusual ability (which Mehta possesses) to navigate one’s way by perceiving the physical surroundings "as sound-shadows by means of echoing sound and changes of air pressure around the ears." As a precocious teenager, Mehta had high ambitions for his future; this important period of his life represented both an opportunity and an impediment, requiring tremendous cultural, emotional, and physical adjustments.

Very well conveyed are the driving desire to be like sighted people, the need for independence and control, and to be accepted in the foreign culture while remaining in some ways superior to it. There are fascinating descriptions of how Mehta learned to travel with minimal assistance, high-dive, package ice-cream in a factory; of how he used money intended for other purposes to build an electronic retreat in a broom closet which allowed him to tape record, type, and to listen to Edward R. Murrow’s broadcasts, and of how he then paid back the money by taking correspondence courses in order to finish school one year early.

The normal adolescent awakening of sexuality, and the ambivalent dependence on parental guidance are also important aspects of the book. Writes Mehta in retrospect,"The three years of my life spent in Little Rock became sealed in a compartment of my mind which I dreaded to open . . . because . . . the near-total submersion in a residential school for the blind seemed to accentuate my blindness, when all along my aspiration had been to be a well-adjusted member of the seeing society outside."
