M: Thanks for agreeing to this interview, Miss Lerner. OK, so I have a few questions. First, when did you know you wanted to write children's books? ,F: Well, I studied creative writing in college, but after I graduated I worked in advertising.

My best friend drew the pictures for me. ,M: And did they like it? ,F: They loved it. A friend of my husband saw a copy in our home and he showed it to a publisher that he knew.
