A thriller becomes great when it carries a feeling of reality and truth.

I have a graduate degree from Penn State. I studied at Penn State under a noted Hemingway scholar, Philip Young. I had an interest in thrillers, and it occurred to me that Hemingway wrote many action scenes: the war scenes in 'A Farewell to Arms' and 'For Whom the Bell Tolls' come to mind. But the scenes don't feel pulpy.

People who know various movie versions don't really know the story.

As much as I like it when a book I'm writing speeds along, the downside can be that an author becomes too eager to finish and rushes the end. The end is even more important than the first page, and rushing can damage it.

You have to follow your own voice. You have to be yourself when you write. In effect, you have to announce, 'This is me, this is what I stand for, this is what you get when you read me. I'm doing the best I can - buy me or not - but this is who I am as a writer.

" ... What if?" Through the alchemy of those two words, something new comes into the world.

When I teach writing, I have a mantra: Be a first-rate version of yourself, and not a second-rate version of another writer.
