Is it a good idea to mention that I'm only 16 in a query letter or should I wait until I (God willing) get a request for a full or partial? I would think it would either be a really big turn off (Oh, this writer isnt mature or even of legal age!) or a turn on (Hey! A teen author! We could get some publicity out of this!) While I suspect it would be the latter, I'm not entirely sure. What do you think?
Don't mention your age. Your manuscript will speak for itself. However, you may need an adult to sign the contract at a later stage.
