The most obvious difference between writing novels and memoirs is that my memoirs are true stories, and explore certain experiences I've lived, and thus operate within the boundaries of memory and fact.

When I was little, I went to a Catholic school and was required to go to church every morning and with my parents on Sundays, so I spent a lot of time sitting on a wooden pew. Angels are sort of a relief. If you're looking around, the other imagery is so dark and heavy. Looking at the beautifully rendered pictures of angels was more uplifting.

Since the Middle Ages, people have been writing about angels. Angelology was actually at one point a scholastic discipline.

I always knew I wanted to write really imaginative fiction - fiction that was very different from my real life.

We create an image of happiness and success and then we are beholden to it. We tell ourselves stories and sometimes these stories become so strong as to imprison us. Breaking free from our personal fortresses is a long, hard journey, but ultimately what allows one to grow.

In terms of style, I think the memoirist should have a novelist's skill and all the elements of a novelist's toolbox. When I read a memoir, I want to really, deeply experience what the author experienced. I want to see the characters and hear the way they speak and understand how they think. And so in that way, writing a memoir feels similar to writing a novel.

One is but a shade of the other.
