In 2015, Eva Holland was forced to confront her greatest fear when her mother unexpectedly had a stroke and suddenly passed away. After the shock and grief subsided, Holland was sent on a deep dive into the science of fear, digging into an array of universal and personal questions: Why do we feel fear? Where do phobias come from and how are they related to anxiety disorders and trauma? Can you really smell fear? (Yes.) What would it be like to feel no fear? Is there a cure for fear? Or, put differently, is there a better way to feel afraid?

On her journey, Holland meets with scientists who are working to eliminate phobias with a single pill, she explores the lives of the few individuals who suffer from a rare disease that prevents them from ever feeling fear, and she immerses herself in her own fears, including hurling herself out of a plane (and in the process, learns that there are right and wrong ways to face your fears).

Fear is a universal human experience, and Nerve answers these questions in a refreshingly accessible way, offering readers an often personal, sometimes funny, and always rigorously researched journey through the science of facing our fears.
