Every time I visit Legendarium Books (my local book dealer of choice), I leave with at least three more novels for my poor TBR. This winter, I hope to make a dent in that list, and to put a spotlight on these seven underrated SF/F books that deserve attention before looking ahead to 2027.
For the purpose of my recommendations, I’ve defined “underrated” as fewer than 10,000 Goodreads ratings. This doesn’t mean these books are unloved by any stretch. Just that they deserve even more attention than they’re getting!
Underrated 2026 SF/F Books
