Martin Luther King's public life lasted only 13 years - yet in that time, he changed the USA's attitude to civil rights forever and continues to inspire human rights movements today.Richard Reddie has written the first book on King since Barack Obama became US president and considers whether Obama is the fulfilment of "King's dream".Reddie seamlessly melds King's religious, social, political and racial ideas in ways that are understandable, yet sophisticated; and captures his legacy and impact on both sides of the Atlantic.Reddie uses copious photographs throughout to chronicle the great man's life and times.As the first Black Brit to write a book on Martin Luther King, he brings a fresh new perspective.
