Jonathan Kozol

'Death at an Early Age' was about racial segregation in Boston. 'Illiterate America' was about grownups who can't read. 'Rachel and Her Children' was about people who were homeless in the middle of Manhattan.

'Amazing Grace' is not a book of interviews or onetime snapshots. It's a memoir of a journey that took me into a place I had never been and took over two years of my life. I don't think the people in this book would have said the things to me that they did if they perceived me as a reporter.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
