Lewis: It really didn't start out as a book project—just an exercise. A few months into it, though, I felt we were on to something. I loved the writing and stories that I was getting back from Susan. We didn't talk about what we were doing. Our discussions really went no further than my e-mails back to Susan each week with exclamations like, "Oh my god!" or "In tears!" or "Wow, how did you go there!?" When we were almost at the year point I told my brother, a designer, about the project. I handed him a pile of folders with pictures and words, and before I knew it we had a rough draft of a book.
