Something you might not know about book world: in the era of online shopping, not every book makes it to the shelf for you to browse. Here are a few great debuts you can request at your local B&N and indies to make sure everybody gets to see them! (Credit to @mossyair.bsky.social for the graphic!)

A 19th century bookplate featuring an illustration of a library with a bust of Shakespeare alongside a portrait of Darwin, a copy of the Venus de Milo alongside a microscope. The Latin on the bookcase reads "books are friends, nature is God.” The image caption reads 2025 Dark Academia Debuts available to buy or pre-order now. There’s a footnote mark on the word Dark.

A cropped banner version of the bookcase from the last image with the caption Dark Academia Debuts available to buy or pre-order now. A flag that reads adult precedes images of the covers of Higher Magic, The Book of Autumn, The Belles, and Doll Parts. On the next row, the covers of The Art of Exile, The Library of Lost Girls, Boys with Sharp Teeth, and Secrets of the Blue Hand Girls are followed by a flag that reads YA. The footnote beneath the books reads Footnote I. Because genres are mushy and darkness is a matter of perspective, light and magical academia have also been included. Happy reading!

Putting footnotes in my book promo like the absolute nerd I truly am.

Anyway! It’s graduation season and maybe you’d like some dark and magic academia in your lives? #BookSky #2025Debuts #BookRecs
