Just updating with a link to a writing tips YouTube channel – Writing with Jenna Moreci. I was told about this by a teen in my writing group who’s found it really helpful.
Jenna Moreci is an American YA dark fantasy and sci-fi writer and she makes short (and hilarious) videos about loads of different aspects of writing. They’re really very funny and entertaining as well as informative. (Some adult language and content so this is maybe for older teens, or if in doubt check them out yourself first).
These are great tea-break fodder and might be good for your writing group to use over the summer to keep them inspired! Check them out!
