49 books like The Paths Between Worlds

Magical doors that appear out of nowhere, a fantastical book that may not be fiction, some truly sketchy villains, a quest, and an intrepid heroine.

The author had me at fantastical book, but what I love about this novel is the world and character building, that feeling of opening the cover and being somewhere that has nothing to do with ordinary life.

And yet, there is mystery. And romance. A lost father. A daring daughter. You’ll want to race through it, but slow down at the same time, just to savor the ride.

Have you ever read a sequel that was better than the first novel?

The Subtle Knife is that book for me.

While it falls in the middle of the complete trilogy known as His Dark Materials, The Subtle Knife takes the story in a new direction by centering it on a knife with the power to cut a path between worlds.

The series follows young Lyra, her daemon Pantalaimon, and Will, a boy she meets who happens to be from a parallel universe. The worldbuilding of this series is some of the best I’ve ever seen, and it truly sets these books apart.

The concept revolves around how Lyra and Pantalaimon are connected. They are two creatures who share a soul. Lyra’s a person, and Pantalaimon is her daemon (think “soul made manifest”) with the power to transform into a fox, hawk, lizard—or any animal he so chooses. At… show more.

When a retired army infantryman knocks down a double brick wall in the basement of his new house, he discovers a doorway and a note pinned on the other side.

Fastened by a knife, the note tells the story of a man who lost his son in this portal. He bricked it up so no one would have to suffer as he has.

Does our soldier listen? Of course not.

Alex Hawke doesn’t go through the doorway unprepared, but he is certainly not ready for what he finds.

A tribe of giants who don't speak a lick of English. 

Massive pterodactyl-like creatures that make a concerted effort to quarter and eat him.

All Alex was trying to do by removing that brick wall was make his new house into a home for his young daughter.

Instead, he finds himself pulled through into another world, forced into the adventure of a… show more.

The other novels I’ve listed here are optimistic, hopeful stories.

This one takes us on a dark and bloody path.

In The Mirror Empire, two nearly identical worlds populated by violent people and sentient (also violent!) plants are at war with each other.

The only doorway between them is powered by blood.

The limitations of this concept are fascinating. Since the worlds are duplicates of each other, each person who lives in one world has a copy of themselves living in the other.

The twist? A person can only cross to the other side if their imposter is dead.

Talk about consequences!

This novel is incredibly bloody and full of betrayal. It’s violent, but the intense action had my eyes pinned open late into the night. 

The Mirror Empire is often gory and frequently shocking, but two things are for sure: You won’t be able to predict what’s… show more.

Late in the 20th Century, an ‘accident’ occurred whereby nuclear bombs detonated in orbit above earth—the resulting radiation has rendered mankind sterile. Algy Timberlane—aka ‘Greybeard’—is in his mid-50’s, a veritable stripling in an increasingly geriatric world. He, his wife Martha, and a few aging friends set off on an odyssey down the river Thames, to explore what’s left of their crumbling, dying world—and maybe find some spark of hope for the future.

Greybeard is a marvel to behold.  It’s one of the few books that’s not only about the hideous injustices of growing old, but also about a world that’s grown old and is facing death. What would people do if they knew that theirs was literally the last generation, that there would be no one to carry on their work? It’s an unsettling question to wrap your mind around—but Greybeard faces it without flinching, and with moving, thought-provoking… show more.

Isaac Asimov rarely wrote about aliens, but this Hugo and Nebula award-winning novel contains an astounding thought experiment, not only imagining a truly alien species but placing them in a different universe with different physical laws from our own.

I first read this novel as a teenager and was blown away by Asimov’s ability to make me understand and care about the fate of such vastly different alien creatures that possessed three distinct sexes and derived their life energy from photosynthesis.

The fact that the novel inextricably links the fate of these creatures with the fate of our own universe gave me a greater appreciation of how truly diverse life can be. A fact–along with the lessons I learned from the other novels listed here–that continues to inform my own writing on aliens and alien cultures. 

The Star King is one of the first science fiction romances I read. It has everything I want in a space opera – politics, fast-paced action, danger, drama, angst, all mixed up with a great love story. I fell in love with the characters, especially the dishy alien alpha male. And I particularly like that the romance is between two mature people with life experience. 

Vance is one of the best Sci-Fi authors of the twentieth century, although for a long time he wasn’t a household name in the genre. Over 70 years he has written an abundance of books, all of which focused on distant worlds and human societies that have differentiated into freedom-loving, anarchic and weird cultures. “Planet of Adventure” is a set of four books, and deals with Adam Reith, a single astronaut stranded on a planet ruled by four races of extraterrestrials. Humans are little more than slaves on this planet, and Adam needs all his wits to survive… and to find a way off the planet and back home. The book resembles a wild, expressionist painting; the extraterrestrials and their strange cultures and the humans that serve them provide the color and texture to a truly amazing adventure.

Multidimensional books tend to focus on either the existence of higher and lower dimensions, or on parallel universes. The Dark Forest (book 3), like my novel, is one of very few that take the string theory approach rather than show parallel universes.

The Three-Body Problem is an epic three-novel series that takes you from the cultural revolution in the ’60s, all the way to…well, the end. There’s a lot of cryogenic freezing to get the main character through time. 

The final theme of the series, introduced in The Dark Forest, is the unfolding and collapsing of dimensions. In the first book, a radio telescope operator finds out that we aren’t alone. A battle with the alien species ensues, including a scene in the Panama Canal that convinced me to spend a few days visiting the modern marvel. It’s well worth the 1500+ pages.

Before writing this little gem, the author produced some of the most notable Star Trek novelizations. Then she decided to create her own version of Star Trek and do the stuff she couldn’t do there. The first volume of a series, it kicks things off when the science crew of the good ship Starfarer, upon learning that their brand-new ship is about to be turned over to the military and become a warship, decides to take matters in their own hands and hijack their own starship. Space adventure at its best.
