I am a lawyer-turned-children's writer. Before I made this happy transformation, I ghost wrote a law book. I am now applying to attend a children's writer's conference. The application asks me to describe my professional writing career. Can I name the book and say that I ghost wrote it, or do I have to use some sort of euphemism like "primary contributing author"? I worked on it for about a year, and I would like to specify the name, if it's acceptable to do so. I am not contractually restricted from naming it, but I don't wish to violate any unwritten ethical code.It is a little dicey to tell strangers about your ghostwriting jobs. As it's not in your contract (as it would be in many ghostwriting instances), you can talk about it, but you may make people a little uncomfortable if they're wondering whether you should be mentioning it.
I think more to the point is that previous publication in law (or physics, or finance, or pretty much any adult topic) does not say anything about your ability to write for children. No, take my word for it. I've met and been submitted to by lots and lots of people who are published writers in one way or another, but their writing for children stinks like feet.
This is not to say that your writing stinks like feet. I am going to assume that your writing smells like lilies and peppermint, and publishers are going to turn your head and ruin your sense of economy with all the money they throw at you. But until that happens, seriously. The law book you wrote means nothing.
