John Kirwan was one of the most devastating wingers New Zealand, and world, rugby had ever seen. A prominent and revered figure at the dawn of the professional age of rugby, he seemed to live a charmed life.

Nobody knew, though, that behind closed doors 'JK' was living a life of tormented fear. Afflicted with depression for many years – including those as a high-profile sportsman – Kirwan was able to survive by reaching out, seeking help from those closest to him.

All Blacks Don't Cry is John Kirwan's story of hope, of working through the pain and living a full life – a poignant, inspirational and helpful example for anybody battling depression.
