I signed up for Canva, something I'd been considering doing for a while. It allows users to create graphics for social media posts, banners, etc. I think you can also make a book cover in there, as well. I'm going to experiment with some graphic/tag line combos to get the word out about my books.
Here's one for Nightshade that I did.
This could be fun, coming up with tag lines and/or pulling quotes from the books. Hoping it sparks some interest.
