There are many different ways to be poor in the world but increasingly there seems to be one single way to be rich.

I recently spoke at a university where a student told me it was such a shame that Nigerian men were physical abusers like the father character in my novel. I told him that I had recently read a novel called American Psycho,and that it was a shame that young Americans were serial murderers.

About 52% of the world's population is female. But most of the positions of power and prestige are occupied by men. The late Kenyan Nobel Peace Laureate Wangari Maathai put it simply and well when she said 'The higher you go, the fewer women there are.'

He was already looking at their relationship through the lens of the past tense. It puzzled her, the ability of romantic love to mutate, how quickly a loved one could become a stranger. Where did the love go? Perhaps real love was familial, somehow, linked to blood, since love for children did not die as romantic love did.

How easy it was to lie to strangers, to create with strangers the versions of our lives we imagined.

I think my first general rule is that most of my experiences are not that interesting. It's usually other people's experiences. It's not that entirely conscious. Somebody tells me a story or, you know, repeats an anecdote that somebody else told them and I just feel like I have to write it down so I don't forget - that means for me, something made it fiction-worthy. Interesting things never happen to me, so maybe two or three times when they do, I have to use them, so I write them down.

I think it's important to humanize history; fiction can help us remember. A lot of books I've read in the past have been so much more important than textbooks - there is an emotional connection with one particular person. I'm very much of a research-is-important type of fiction writer, even for contemporary fiction. I wrote about blogs in America and I've never blogged. But I read many, many blogs - usually about feminist things, or about race, or about hair.
