When everyone's focused on the conventional parts of war - doing infantry imbeds or chasing IEDs - you look at the thing that seems not that interesting to people, like the circumstances of logistics workers cooking the troops' food or cleaning their latrines.

I feel like I partly came to writing through being in college during the start of the Iraq war, and knowing that those issues mattered lot to me, and wanting to go see for myself.

The tremendous challenge of narrative journalism about subjects that are underreported is, how do you make people care about something they think they already know about, or think they don't need to know about?

For me, the part of reporting that's the most rewarding and energizing is just hearing directly from people whose voices haven't often been heard, or incorporated into mainstream media. That stuff is really, really gratifying, and so to realize that you could make a career of that part of it, that appealed to me.

I think most of us, as writers, have had experiences where you get edited and it doesn't feel like your voice at all. And so it's been nice to go through the experience of having a lot wind up on the cutting-room floor, and yet still feel that your voice is being - not purified, but made more yourself. I think that's a very rare thing.

I found it really astonishing that undocumented migrants were kidnapped so routinely, that it was such a commonplace part of the journey for people trying to reach the US, and that we hear almost nothing about it here.
