It's very difficult to put in the work unless you believe that what you're doing is significant in some way.

The editor, Stephen Segal, actually called me with the idea of creating an accordion book [ "The Thorn & The Blossom"], and asked if I could write a story for it. I was so intrigued! I immediately knew that it had to be a love story told from the points of view of the two main characters. Right away, I started working on a proposal. And once I had my main characters, Brendan and Evelyn, it was as though they started telling me their stories.

I would tell myself to get more sleep! Believe it or not, I wrote the book while finishing my PhD in English literature. It was wonderful to get away from doing literary scholarship by writing this mythical love story. I think so much of my own love for books and scholarship comes through in The Thorn and the Blossom.

Jorge Luis Borges wrote a poem when he was in his 80s about one day writing the book that would justify him. This was long after he had become one of the great masters, a writer everyone looks up to and reveres. As artists, I don't think we ever see ourselves as done. We always think we're at the beginning . . .

When we tell stories about things that are important - love, fear, beauty - we change the way people think about the world. Writers are, or should be, truth-tellers even when the stories themselves are fantasy.

Sometimes you have to follow your uncommon sense.

If readers like The Thorn and the Blossom, which I would call literary fantasy, I think they would like books such as Elizabeth Hand's Mortal Love, Catherynne Valente's The Girl Who Circumnavigated Fairyland in a Ship of Her Own Making, and Kelly Link's Stranger Things Happen.
