2Richard Wilkinson is the co-author of the book 'The Spirit Level: Why More Equal Societies Almost Always Do Better'. He says that inequality is divisive and socially corrosive and that economic growth beyond a certain level no longer delivers social benefits. New Zealand is now around the fifth most unequal society in the Western world - a product, Wilkinson tells Chris, of changes to our society in the late-1980s that led to the most rapid rise in inequality of any rich nation. 'The Spirit Level', by Richard Wilkinson and Kate Pickett is published by Penguin.

3David James Smith's 'Young Mandela' goes beyond the Mandela we know today -- the president, the elder statesman -- and investigates Mandela's early years.

The book reveals messy relationships, the flaws and weaknesses of the man who lead his country to freedom. 'Young Mandela' by David James Smith is published by Orion.
