Leo had been blind since birth, but he’d never felt disabled. He had his cane, his dog, Juno, and a memory palace of sounds. He knew his neighborhood in Atlanta by its symphony: the arrhythmic thump of the MARTA bus brakes, the gossipy squeak of the Piggly Wiggly cart wheels, the low harmonic hum of the power substation on Peachtree.
