I have sat with the mothers who have lost addicted sons. I have sat with families of kids who have been killed in drug-related gang violence. I have been to the prisons. I have seen the effects. At some point in time, I felt I had to do something other than write a novel about it, that I needed to try to make some sort of contribution, at least try to make some sort of difference in the real world.

It's important to me that the reader goes on a ride with the characters, that you set context enough to know, "Okay, here's where we are in the world. Now we're just going to go inside this person's head, this guy's heart, this woman's ambitions and take it down to very, very small scale."

American cops are the ones who are in the emergency rooms. They're the ones who go to the morgues. They're the ones who have to go tell the families that their son is not coming back, their husband, their wife, is not coming home that night. So when we talk about guns and gun violence and police, let's understand that as well. No one wants guns off the streets more than cops because cops are killed by those guns.

I don't recognize myself. I don't know who I am anymore." And it's all fun and games until someone loses an I.

I was researching some of the modern-day figures that The Sopranos were moulded on. So many iconic Sopranos moments. James Gandolfini and Edie Falco had an incredible scene together in the kitchen of that house that looked like it was about to explode. That was an iconic series that changed the way we did television. It is also an extremely realistic portrayal of the mafia. Much more so than The Godfather. The Godfather, one of the greatest films ever, but let's face it, a romanticized version of the mob.

I've been writing since I was six years old. It's hard to imagine stopping. I would hate to think that I've already written my best book.

We need to do something about gun violence in America. But every time one of these things happen, we say the same thing, and then we don't seem to be able to do anything. And that needs to change.
