I run teen writing groups on Outschool and one of my teens just formatted her entire book in Affinity Publisher. She really enjoyed the software a lot. On the down side, though, she couldn't find any way at all to export to an EPUB to make an ebook out of it. Have you done any work with EPUBs with it? Or does it only handle a basic PDF?
