I am Princess X is a unique mix of webcomic and prose. Set in Seattle, it's a mystery, a thriller, and a look into a lifestyle that includes the literal Seattle underground and the dark web.
Here's a quick booktalk you can use:
May is 16-yrs-old when she begins seeing stickers and graffiti of Princess X throughout Seattle. When May was younger, she and her friend, Libby, created the Princess X comic. May wrote the story and Libby illustrated it—but that was years ago—before Libby died. So who's drawing Princess X now?
I think it's a sleeper hit, that will only become more popular with time. It received starred reviews in School Library Journal, Publishers Weekly, and Booklist.
