50 books like Doors of Sleep

This book explores a parallel world, a familiar world like the protagonist’s but a mixture of a better and worse one, what could keep her there, and wanting to get out.

I watched the adapted film first then read the book, in a way, seeing them both is like looking at two different universes like I’ve been looking at the Other Coraline book. I recommend reading the book if you have seen the film, to spot differences but still enjoy a journey.

And it is a great journey even if the book is your first exploration in the story.

Being someone who often ponders life's "what ifs," I was quick to snap this novel up. The plot revolves around a suicidal woman, Nora Seed, who finds herself in a mysterious library between life and death, where each book serves as a portal to a different version of her life had she made alternative choices.

Though the story shares thematic elements with traditional time travel narratives—such as the exploration of alternate realities—it’s not time travel in the strictest sense. Instead, it has a dreamlike quality that offers a clever means to explore the deeply personal and relatable concept of self-discovery.

As Nora samples all the different lives she could’ve lived, I couldn’t help but reflect on my own life choices and the paths I didn't take…and be grateful for the ones I did.

For those who don’t want to read a novel length but want to experience worlds beyond worlds, this book I would recommend, a neat short story where the protagonist uses the multiverse as a form of self-discovery, experiences he would never have in his own life and considers to a change of character.

Might not be a full-blown adventure, but a calmer mundane life experience, relatable while simplifying the multiverse without any complexities. 

Though it never mentions the word ‘multiverse’, it has many aspects of a story about travelling through worlds beyond worlds, going somewhere from nowhere, taking things that don’t exist in another place.

I found this book interesting because it includes a mystery, as the protagonist goes through her journey, she uncovers mysteries and hidden truths about her abilities.

A different concept of multiverse travelling, as well as worlds that are aware of each other, it was still an interesting read that leaves a satisfying conclusion.

Rifts happen, so you should be ready when universes collide. A policy with Stranger & Stranger can cover all of your interdimensional insurance needs. But Tom Stranger faces his greatest challenge yet. Despite being assigned the wrong—and woefully inadequate—intern, Tom must still provide quality customer service to multiple alternate Earths, all while battling tentacle monsters, legions of the damned, an evil call center in Nebraska, and his archnemesis, Jeff Conundrum. It's time to kick ass and adjust claims. This is my go-to for road trips. Tom Stranger is such a straight man, but the humor never stops.

This is the book that launched my Zelazny obsession as a teen. Carl Corey wakes up after a car crash with amnesia (sense a theme here?), which he hides from those close to him, some of whom insist on calling him Corwin. He gradually discovers he’s an immortal with a strong claim to the throne of Amber, the one true world at the center of infinite shadow worlds, including our Earth. As Corwin’s memories return, he realizes he was a cruel and arrogant man, and some of his numerous siblings have good reason to hate him. Here the amnesia trope truly allows a character to examine their past through a less biased lens. Top-rate fantasy set against a war for succession to the keys to the universe.

L.D. Lapinski’s incredible Strangeworlds series will definitely sweep you into another world – into as many other worlds as you can count! Step into your suitcase and go on a journey to somewhere beyond imagining with Lapinski’s amazing cast of characters. When Flick stumbles into a dusty old shop and meets a young man named Jonathan Mercator, it’s the beginning of a life-changing adventure – across the multiverse – for them both.

Elric of Melnibone is an anti-hero. He is a bad guy who worships a god of chaos and delights in doing bad things. Pressured by family, a sense of duty, and a deep devotion to both his lover and his friends, he begins to question his life and his culture up until now. The lack of caring weighs on him as he vacillates between a world of evil and chaos and a world of law and goodness. 

Combining a murder mystery with a colorful sci-fi universe that’s full of magic? Yes, please. Odd couple Lieutenant Iari and Ambassador Gaer (who, don’t let the title fool you, is actually an alien spy) have to team up to discover why a retired battle-mecha killed someone—an occurrence that should be impossible. The rapport between Iari and Gaer is a delight, and the plot quickly unfolds from a mere murder to something far more sinister. I absolutely love the world that Eason creates—it has the scale of a video game-like Mass Effect while simultaneously creating compelling characters. 

This book is a delirious romp through time and space with a political edge, which is enough to make me love it on its own. However, versions of the main character, Jerry Cornelius, pop up in just about all of Michael Moorcock’s work, including The Dancers at the End of Time trilogy, the Elric of Melnibone books and even his Dr. Who novel.

But wait! There’s more! Moorcock gave other writers permission to use the character, so he appears in other people’s works (including one of my novels). One of the first explorers of the concept of the multiverse, Michael Moorcock brilliantly paved the way for the rest of us.
