When I was doing 'Smile,' I was looking back at pictures of myself and going, 'Thank goodness I couldn't do the sprayed-bangs thing! Everybody's so embarrassed by that hairstyle now, but I was never cool enough to pull it off!'

Typically, a book is published and gets one season in the sun. Eventually, you write another book, and maybe your old books get a bump, but my books seem to keep being discovered and recommended to new people of all ages.

All of the narration in 'Smile' is first-person. Most of the books that I grew up reading had first-person narrators for some reason. My diaries were written in this voice, and since this story is autobiographical, it just felt like a natural extension.

I prefer drawing the things I've written to handing them off to another artist. Turns out I'm a huge control freak - and because I write in thumbnails, the art is already happening by the time I start writing!
