Alix E. Harrow's highly-anticipated tie-in novel to her short story "The Six Deaths of the Saint" finally arrives this month, and we couldn't be more excited. So excited that we're serializing the first few chapters!
FANTASY
The Isle in the Silver Sea
TASHA SURI
Two ladyknight books for a ladyknight fall: Tasha Suri's The Isle in the Silver Sea follows a knight and a witch doomed to fall in love again. And again. And again... Christina Orlando describes it as "a little Inkheart, a little Starless Sea."
This month in YA releases, you may expect the hunt to expose a monster with lots of eyes (A Feast for the Eyes), an operation to infiltrate a post-apocalyptic version of The Bachelor (An Ocean Apart), and a campy romantic horror perfect for fans of The Summer Hikaru Died (He's So Possessed With Me). So, which one first?
Olivie Blake's back with a horror/thriller satire following two women desperate for acceptance in a sorority house, even though this one seems have some very...unusual requirements.
SCIENCE FICTION
All That We See or Seem
KEN LIU
You may already be familiar with Ken Liu's short fiction collection The Paper Menagerie and Other Stories or silkpunk fantasy series The Grace of Kings, but All That We See or Seem is his first science fiction novel, merging a cyberhacking thriller with discussions of identity, artistry, and AI.
We've successfully quarantined the horror books of October 2025 into one easily digestible directory. Unless, of course, you choose to unleash them, and embrace the terrors inside...
What does it mean to be "SFF-Crossover"? Books that fall under science-fantasy, anthologies, the occasional nonfiction... You'll find everything that refuses to be defined in this list of all the SFF Crossover books of October 2025!
Trust us on this one: S.T. Gibson's gothic romantasy perfectly melts together Scottish moors, haunting family history, and tangled romantic tension. It's Wuthering Heights with a folkloric bite.
YOUNG ADULT HORROR
And The River Drags Her Down
JIHYUN YUN
Well...we wouldn't leave October's new books without one more horror recommendation. Everything seems fine when Soojin Han defies the rules to bring her older sister back from the dead...until she gets hungry.
