A striking debut work of experiential reportage illuminating what fear does to us and how it’s key to both staying and feeling alive. In the vein of Mary Roach, Holland thrusts herself onto the front lines of daring adventure and cutting-edge research to explore universal human questions: How do we feel fear? And why? By jumping out of an airplane, learning to rock climb, speaking with leading scientists, and subjecting herself to the latest pharmacological and exposure therapies, she comes ever-closer to knowing: Is there a better way to feel afraid? By building up the nerve to face down her phobias, Holland shows us not only how to thoughtfully grapple with (and even perhaps overcome) our fears—but also how to live happier and feel more alive—by embracing them.
