I got another critique of my Ferret story at the SCBWI Conference on Saturday; and, like the others, this editor felt that it needed to be in prose instead of poetry. She, too, liked the idea; but like another editor, didn't know how to market it. So in addition to having trouble getting the rhymes to work, I may be doing all this for nothing.
No, I'm not given up on my Ferret story, but I am putting it aside for awhile and thinking about how I can change it back to prose, keep it fun, and make it marketable.
In the meantime, I have a new idea I'm working on for a kids book - it's about circles and squares. I'm also working hard developing characters for my 60's era novel. Must keep writing!
