The most successful hyperpowers are the ones where there was actual intermixing. Tang dynasty China was China's golden age, and contrary to what I was told when I was growing up, Tang China was founded by a man who by today's standards was no more than half Chinese. It was a mixed-blood dynasty that pulled in 'barbarians' from the steppe.

I saw my parents come over. They were immigrants, they had no money. My dad wore the same pair of shoes, I had some ugly clothes growing up, and I never had any privileges. In some ways, I think the person that I am now, I think it's good that I had that kind of tough upbringing.

Some people don't need parental commitment, they will still come out great, but for others, parents can be critical in providing moral and academic guidance.

I sort of feel like people are not that honest about their own parenting. Take any teenage household; tell me there is not yelling and conflict.

Ideally, I'd like to keep a balance between action and romantic roles.

Two best friends can totally say they love and adore each other, without any meaning of romance.

In the book, I write about children in first grade who were taught to read by reading want ads. They learned to write by writing job applications. Imagine what would happen if anyone tried to do that to children in a predominantly white suburban school.

I can't explain something I saw on holiday on Holy Island when I was about nine years old, but do you know what, it could have been my PE teacher dressed in a monk's habit. I have no idea. I'm not a ghost person... it doesn't mean there aren't unexplained things; I just don't think they're ghosts.
