The Best Science Fiction & Fantasy Books of 2021 (Anticipated)

2021 science fiction sci-fi and fantasy books novels sff anticipated new releases

There are a ton of great science fiction and fantasy books in store for 2021. Of these upcoming new releases, the one I’m the most curious about is probably Project Hail Mary by Andy Weir (of The Martian fame), but there’s also a lot of other fantastic titles planned as well. And hey, who knows, maybe George R.R. Martin will finally release The Winds of Winter? I’m including it on this list, but I do realize of course there’s a good chance it won’t get released.

Anyway, in case it wasn’t clear, this is a list of The Best (Anticipated) Science Fiction and Fantasy Books for 2021, divided up into Adult/General and YA titles. If you have any suggestions of titles to add, feel free to drop a comment below!

For more books coming soon, see the list of Upcoming New Release Books.

This post is sponsored by LMBPN but all opinions are entirely my own.

Also, please check out the sponsor of this post. LMBPN publishing is offering free downloads of their highly-rated sci-fi novel Obsidian Detective (Book #1 from the Opus X series) by Michael Anderle.

Obsidian Detective is about two rebels from different planets whose worlds collide. One, young and idealistic, comes from the elite and peaceful earth civilization. The other, a cynic and a survivor, comes from the fringes of society, where military might reigns.

Together, they’ll work to uncover the secrets behind a plan to set off the first intergalactic war between humans and an alien race on small moon in a far off system. It’s a cover-up that has left a trail of bodies in its wake.

For a tale of science fiction, mystery, aliens, AI, intergalactic corruption, download Obsidian Detective (Book #1) for free below.

All he knows is that he's been asleep for a very, very long time...
