I still haven't had any feedback on my submissions letter.
It's really difficult to know what to put in one of these, and this is my first attempt. I was desperately hoping that a friend-of-a-friend (who is a published author) would offer some pointers. They said they would, but haven't got back to me. I don't like to be pushy, after all, they are working to deadlines themselves.
I think I just have to be brave, and trust in myself.
