"Allen Shawn is afraid of heights, water, fields, parking lots, tunnels, and unknown roads. He avoids subways, elevators, and bridges. He is afraid of both closed and open spaces and of any form of isolation--yet this is a memoir of enormous bravery. He is the son of New Yorker editor William Shawn and brother to playwright/actor Wallace Shawn. His twin sister is autistic. His father led a double life that introduced strict taboos to his household.
