Like most New Yorkers I was shell-shocked immediately after 9/11 and couldn't put into words what I was feeling.
When I was writing 'The White Tiger' I lived in a building pretty much exactly like the one I described in this novel, and the people in the book are the people I lived with back then. So I didn't have to do much research to find them.
For 'X-Men' I was lifting a lot of weights. I actually lost a lot of mass when I quit 'X-Men' because I was working out so much and very muscular and strong.
