This email is a list of all the new science fiction, fantasy, and other genre books coming out in September 2025. We hope you find your next favorite read!
This month you can expect more Witcher, Arthurian retellings (Morgana's edition), and a new Naomi Novik novel about a curse to seek fame and glory! Come check out the new fantasy books of September!
For once, this month has a healthy number of new science fiction offerings. A Hell Divers prequel novel, a new Dungeon Crawler Carl installment, and the return of John Scalzi's Old Man's War series make up just a few of the long list of September sci-fi releases!
We'd venture into a cursed forest for this book. Maddie Martinez's The Maiden and Her Monster is a dark, lush retelling of the golem myth, perfect for sapphic September and the start of fall. If you want to get a head start, we've shared the first few chapters!
SCIENCE FICTION
Saltcrop
YUME KITASEI
Yume Kitasei returns with Saltcrop, a "not too distant future" climate novel about two sisters making a desperate journey across a dying world to find their last sibling, who they begin to doubt they ever really knew...
It is a September for the SAINT OF FEAR (Season of Fear by Emily Cooper). It is a September for WEIRD CULTS (The Deep Well by Laura Creedle). But also perhaps...WARY ALLIANCES with PROSPECTIVE LOVE INTERESTS (An Embroidery of Souls by Ruby Martinez)! In other words, it's a great month for new YA releases!
FACT: If you tried to read every book on this list of horror, romantasy, and other SFF-crossover novels coming out in September 2025...it would take a really, really long time. We've got the newest horror anthology edited by Ellen Datlow (Night & Day) and romances between gods and mortals (Wild Reverence by Rebecca Ross). Which are you most excited for?
Andrew Joseph White, author of Hell Followed With Us and The Spirit Bares Its Teeth, is no stranger to horror. But we've been warned that his first adult novel is particularly grotesque. How do you feel about pregnancy horror and...worms? 🪱🪱🪱
FANTASY
Fate's Bane
CL CLARK
Not only does The Sovereign, the finale to the Magic of the Lost trilogy, come out this month, we are getting special treatment with a new novella by C.L. Clark too!! Clark reimagines classic fantasy tropes in this lush tale about love, warfare, and cyclical stories.
