Bruni will be promoting his new memoir "The Beauty of Dusk: On Vision Lost and Found," in which he discusses his adjustment to the terrifying reality of partially losing his eyesight, a medical and spiritual odyssey that involved not only reassessing his own priorities, but also reaching out to, and gathering wisdom from, longtime friends and new acquaintances who had navigated their own traumas and afflictions. Bruni will be speaking at 7:30 p.m. on Friday, Oct. 7, at the Mayo Performing Arts Center, Morristown, in conversation with MSNBC news anchor Katy Tur.
