How would you react to a disaster? Would you be paralysed with fear? Would you panic and lose control? Or might you suddenly discover hidden strengths in yourself?

In The Unthinkable, award-winning journalist Amanda Ripley investigates some of the most harrowing catastrophes in history in order to piece together exactly how we react in a crisis. Through compelling interviews with survivors and experts she uncovers our instinctive reactions, shows how primitive parts of our brains take over when we're put under pressure, and demonstrates that we can, in fact, train ourselves to do better.
