'I can rest only for a moment, for with freedom comes responsibilities, and I dare not linger, for my long walk is not ended.' With these words, Nelson Mandela ended his first volume of autobiography, Long Walk to Freedom.

Now, the memoir that Mandela began while he was still South Africa's first democratically elected president has been completed by the eminent South African writer Mandla Langa, using Mandela's unfinished draft, detailed notes made as events were unfolding and a wealth of previously unseen material. Dare Not Linger tells the story of Mandela's presidential years, from the run-up to that extraordinary election in 1994 to the moment he stood down in 1998.

In that time, Mandela and his government wrought the most extraordinary transformation, turning a nation riven by centuries of colonialism and apartheid into a fully functioning democracy in which all South Africa's citizens, black and white, were equal before the law.

With a prologue by Mandela's widow, Graça Machel, the result is a vivid and inspirational account of Mandela's presidency, a country in flux and the creation of a new democracy.
