Written during his historic 1,000-mile (1,600-km) swim around the entire coast of Iceland, the book follows Edgley as he battles Arctic storms, active volcanoes and one of the largest hurricanes ever recorded in the Atlantic - a journey that moves through Nordic mythology and modern neuroscience to reveal one of the most powerful weapons any human can wield against adversity and suffering: purpose.

Drawing on pioneering research within neuropsychology, ancient sagas and lived experience at the edge of human endurance, How to Hero shows how resilience can be built, trained and weaponised for the moments when life gets hard. We are all, in some form, on a hero's journey. The monsters may be internal, the battles unseen, but the path has always been there - waiting to be remembered. You just have to answer the call.

This is How to Hero.
