My secret vice is Sudoku puzzles. Can't stop playing them. My parents are accountants. I blame them entirely.

When I got my very first phone call that I'd hit the 'New York Times' list, I had a small rush of 'I've made it!' But the next morning, it occurred to me I didn't know what it was, so I called my agent and asked what being a 'New York Times' bestselling author really meant. He informed me that I was now a thousand pound gorilla.

Before I became a suspense novelist, I wrote romantic suspense as Alicia Scott.

Who do you love? It's a question anyone should be able to answer. A question that defines a life, creates a future, guides most minutes of one's days. Simple, elegant encompassing. Who do you love?

I still read romance, and I read suspense. I read them both. And part of it is, I like stories with strong characters, and I like stories where there's closure at the end. And I like stories where there's hope. That's a kind of empowerment. I think romance novels are very empowering, and I think suspense novels are, too.

When it comes to locations, I'm one of those crazy authors who has to see it, touch it, taste it, before I trust myself to recreate it for my readers. Having said that, visiting a locked-down pediatric psych ward was the most intimidating research I've ever done - and I've visited maximum security prisons, shooting galleries, bone collections, etc.

I'm very intrigued by e-books, the topic du jour in the industry today. As a number one bestselling Kindle author, I love the way e-books make an author's backlist accessible to new readers. Of course, price point remains a source of concern. Personally, I don't have any of the answers, but I'm intrigued by the questions.
