Anyone who has written (or understands) writing for middle grades, what common mistakes can I avoid in writing?
I haven’t written a draft yet, but I’ve pretty much fully fleshed out all of my thoughts of what I want my next story to be and I’m itching to get it out. It’ll be a portal fantasy and I believe middle grades will be the appropriate audience. What brief pieces of advice can you give a slightly-above-novice writer?
