I’ve been writing novellas for my kids for the last few months. The writing is fine. The stories, fine. Not mind blowing. The real trick is personalization. Telling stories about the kids as characters in places they know with our inside jokes. They are personalized stories. Written for them. This is key. It makes up for the so-so stories and writing. It’s a lot of work. It’s a heavy collaboration, a lot of careful specification by me of specific details to include.
