I feel more pressure when I'm writing for teens. I'm very aware that my audience is impressionable. Therefore, I'm far more careful about what I say and the language I use.

I watch a lot of teen TV and read a lot of YA novels. I also talk to teens whenever I can. There are cultural differences between when I was a teen and now, but emotions - anger, angst, love - are the same.

I think that if you write what you love to read, that will be what your audience wants to read, too.

I've always wanted to be a part of that experience of writing to an audience that is just starting to fall in love with books. When I felt that my writing for adults had become cemented, I decided to write a YA series.

The year my mom worked as a secretary at an apparel company in midtown, she would often come home in tears because she had mistakenly called her boss by another coworker's name. 'You know how it is,' my father said, 'they all look the same. It's not your mom's fault. There's just no telling them apart. Same high nose and deep-set eyes.'

I think the art world is one of the last bastions of this kind of sexism where there is a mythology about a woman not being able to be both and artist and a mother: that some very important creative crystal inside a woman would be shattered by the idea of having a child.

When my family goes to sleep, I start clicking, combing through digitized phone books, school yearbooks, and Google Earth views of crime scenes: a bottomless pit of potential leads for the laptop investigator who now exists in the virtual world.

I'm doing less than I used to because I'm a family man now, and I have two kids.
