So, you've decided to sit down and get into reading not getting a seventh season, or you're ready to take a break from reading light, fluffy romantasy and want something that's got more going on than sexy fae drama.

The wild world of heavy on the technobabble – or worse, real science – and often stray into some very experimental and existentially challenging forms of storytelling. So, while these books are all (or at least mostly) excellent, beginners should be cautious about jumping straight into the deep end of this particular pool.

10 Dune Messiah

By Frank Herbert (1969)

Dune Messiah by Frank Herbert cover

Frank Herbert's Dune was a novel that was at least as influential on the genre of science fiction as Tolkien's Lord of the Rings was for fantasy; it enshrined tropes and terminology that are still in common use by hundreds of authors today, and has inspired some genuinely incredible film adaptations. The same can't really be said for its immediate sequel, Dune Messiah.

While Messiah is a fantastic second chapter in the Atreides saga, it is a genuinely depressing book, as most of it concerns Paul Atreides and the tragedies he endures while consolidating the Empire he never wanted. By the end, Paul loses almost everything he cares about, and exiles himself into the desert rather than continue down the path of violence that's been blazed in his name. It's a beautiful and poignant moment, but for someone just getting into the genre, it may be a little bleak – and of course, the subsequent Dune books go even farther off the philosophical rails.

9 Anathem

By Neal Stephenson (2008)

Anathem by Neal Stephenson cover

Neal Stephenson is a brilliant but often painfully verbose writer. Some of his other books, like Snow Crash or The Diamond Age, make for decent enough entry points into science fiction as a whole, although they, like the rest of Stephenson's work, rely heavily on metatextual references to make their points; Snow Crash in particular reads very differently depending on whether you've read any of William Gibson's early works. Anathem takes that metatextuality a few light-years further.

Anathem is a deep, philosophical analysis of the many-worlds interpretation of quantum mechanics, which is the sort of thought experiment known to drive physics grad students to heavy drinking. Stephenson further complicates this by using a framework known as Directed Acyclic Graphs, which are a form of topologically ordered flowchart used by biologists, information scientists, as part of the way he frames the exploration of overlapping quantum realities. It's a brilliant exploration of quantum philosophy – and at almost 1000 pages, its better suited as a doorstop than an entry point into science fiction.

8 Dhalgren

By Samuel Delaney (1975)

Dhalgren by Samuel Delaney cover

Samuel Delaney is a genuine master of the American science fiction scene, and Dhalgren is one of his best-selling and most polarizing books. It sold half a million copies in its first year, and Delaney's fellow sci-fi authors have both praised it and damned it, calling it everything from "the very best ever to come out of the science fiction field" (Galaxy magazine, March 1975) to "the most disappointing thing to happen to science fiction" (Outworlds magazine, January 1976).

Dhalgren's incoherent narrative tells the story of the Kid, an amnesiac and possibly schizophrenic drifter who embodies the concept of an "unreliable narrator" so much that the book reads about as easily as James Joyce's notoriously brain-twisting novel Finnegan's Wake. Dhalgren even uses a similar structural conceit to Finnegan's Wake, finishing on an incomplete sentence that connects to its opening line, creating a circular story that further reinforces the Kid's unreliable narration – and further reinforcing the fact that Dhalgren is a book not for the literary faint of heart.

7 Gravity’s Rainbow

By Thomas Pynchon (1973)

Gravity's Rainbow by Thomas Pynchon cover

Thomas Pynchon is widely regarded as one of the Great American Novelists, and Gravity's Rainbow is the book that helped him earn that appellation; on its release it won the US National Book Award for Fiction, and it was nominated for both a Pulitzer Prize and a Nebula Award. The New York Times' review of the book had the headline "One of the Longest, Most Difficult, Most Ambitious Novels in Years."

10 War Books Too Twisted To Be Made Into Films

War films haven't lost their popularity in modern cinema, but Hollywood may struggle with adapting these ten dark and twisted war novels into films.

All of that is to say that Gravity's Rainbow's brilliance is only eclipsed by its complexity. The book features over 400 characters, and many of them narrate in widely contrasting styles and even formats, resulting in changes between chapters from movie script format to stream-of-consciousness narration to fourth-wall-breaking dialogue. It's a phenomenal exploration of military-industrial development and a conversation on free will all at the same time, but it's also potentially incomprehensible to any reader who isn't used to such unconventional stylistic freewheeling.

6 The Andromeda Strain

By Michael Crichton (1969)

Andromeda Strain by Michael Crichton cover

While Michael Crichton's greatest legacy is unquestionably the novel Jurassic Park and the film franchise it spawned, The Andromeda Strain is the novel that put him on the map as the king of 20th-century techno-thrillers. The titular Andromeda Strain is a deadly microorganism that arrived on Earth aboard a military satellite, and the novel's characters – a group of doctors recruited by the U.S. military – must work to understand it before it breaks containment and threatens the globe with a pandemic of unknowable proportions.

Writer Michael Crichton launched franchises like Jurassic Park & Westworld as a novelist, screenwriter & director; we rank all of his sci-fi movies.

The Andromeda Strain was a phenomenal success for Crichton as a novelist, yet the interceding 50 years since its publication have resulted in a novel that hasn't aged particularly well. There's a good amount of implicit misogyny in the book's very bones, which was certainly common in the military and scientific communities at the time but reads poorly today. The Andromeda Strain also doesn't quite have the balance between plot and technobabble that Crichton's later books handled better, making the frequent forays into dense discussions of Andromeda's biology an exercise in patience for readers without a postdoctorate fellowship in virology.

5 Starship Troopers

By Robert Heinlein (1959)

Starship Troopers by Robert A Heinlein cover

Heinlein's Starship Troopers is the Lord of the Rings of military science fiction; intentionally or not, everything in the genre that has come since has been influenced by it. Whether it's other novels like John Steakley's Armor and Joe Haldeman's The Forever War, or the entire concept of armored super-soldiers seen in gaming franchises like Warhammer 40,000, Halo, or Doom, they all lead back to Heinlein's Hugo Award-winning book.

Starship Troopers' Secret Meaning Explained: What It Was Really About

Starship Troopers is more than a cult classic sci-fi action movie about soldiers killing space bugs, and its secret meaning harshly criticizes the US.

Yet, for all its praise and contributions to the genre, Starship Troopers is also a seriously polarizing book. Even to this day, scholars can't agree on whether the novel is a celebration of a militarized, fascist, human-supremacist society, or a satire of one, although it's the latter interpretation that fueled Paul Verhoeven and his brilliant 1997 film adaptation.

The book is also crammed with heavy philosophical and civic-minded infodumps that occasionally read more like a textbook than a novel, as well as some painfully hyper-masculine chauvinism. As a result, while certainly an influential and occasionally thrilling read, it's best for a sci-fi neophyte to just watch the film first and slog through the novel later.

4 Ringworld

By Larry Niven (1970)

Ringworld by Larry Niven cover

Ringworld was the first novel Larry Niven wrote in his Known Space universe, which he had spent the 1960s exploring via short stories. The change to novel format resulted in Niven making an impact on science fiction approximately as large as the titular Ringworld – a massive construct encircling a star that provides enough surface area to fit several million Earths, packed with odd and often primitive inhabitants. Ringworld's influence can still be seen today, most notably in Halo, but similar megastructures have also appeared recently in both Star Wars and Star Trek.

For all its influence, however, Niven's Ringworld has aged extremely poorly. If Heinlein's Starship Troopers is chauvinistic, then Ringworld and its depictions of gender are downright misogynistic, with protagonist Louis Wu developing an almost pro forma sexual relationship with walking plot device Teela, who herself is a descendant of one of Louis' former lovers. Ringworld's overall story is a good one, but first-time readers are heavily advised to check their modern sensibilities at the door.

3 Red Mars

By Kim Stanley Robinson (1992)

Red Mars by Kim Stanley Robinson cover

Kim Stanley Robinson's Mars trilogy, of which Red Mars is the first book, may be one of the most heavily-detailed essays on terraforming and interplanetary colonization ever written. The series spans the years from 2026 to 2212 and follows several generations of colonists as they work to transform Mars from an inhabitable desert to a utopian paradise and, along the way, find ways to genetically engineer themselves to better fit the biospheres of new worlds.

However appealing they are as a potential future, though, Robinson's books are a little heavy on the ecology and a little light on the plot to be a good entry point into reading science fiction.

Red Mars and the rest of the trilogy are brilliant books, fascinatingly and accurately positing a future where such interstellar colonization efforts would require the backing of not just national governments, but also transnational corporations that are actually competent and helpful contributors to the colonization efforts rather than the vainglorious bumbling of an egomaniacal oligarch. However appealing they are as a potential future, though, Robinson's books are a little heavy on the ecology and a little light on the plot to be a good entry point into reading science fiction.

2 Slaughterhouse-Five

By Kurt Vonnegut (1969)

Slaughterhouse-Five by Kurt Vonnegut cover

Kurt Vonnegut, another one of America's greatest authors, clearly drew on his experiences as a German prisoner of war in Dresden during the Second World War when writing Slaughterhouse-Five, given that the book's protagonist Billy Pilgrim endures a similarly harrowing experience. Unlike Vonnegut, though, Billy is abducted after the war by the alien Tralfamadorians, who place him in a zoo with a porn star for a mate and send him flashing back and forth through time.

Slaughterhouse-Five Review: Eisner Winners Revive a Literary Classic

Kurt Vonnegut is one of the most respected authors of his time, with his opus being Slaughterhouse-Five, and now it's being retold as a graphic novel.

Everything about Slaughterhouse-Five, from its brilliant nonlinear structure to its powerful anti-war message, makes it clear that the book has deserved every iota of praise it has received over the years. Yet that same nonlinear structure, and the raw power of how it explores Billy's (and by extension, Vonnegut's) traumatic experiences in the war, make it hard to recommend as anyone's starting point.

1 The Quantum Thief

By Hannu Rajaneimi (2010)

The Quantum Thief by Hannu Rajaniemi cover

Finnish-American author Hannu Rajaneimi's debut novel was well-received on its release, and praised for its engaging characters and thrilling plot – an interplanetary heist patterned after the stories of French author Maurice Leblanc and his famous protagonist, Arsène Lupin. It was nominated for a Locus Award and the Campbell Memorial Award, and although it failed to win either, Rajaneimi went on to write two sequels, The Fractal Prince and The Causal Angel.

Lupin is quickly becoming a popular thief thanks to the Netflix series. He s a long list of gentlemen thieves from cinematic history.

Yet for all The Quantum Thief's clever writing, Rajaneimi pulls few punches as an author and comes down heavily on the "show, don't tell" side of the science-fiction style guide. While other authors' work makes for a difficult entry point into the genre because of their heavy use of exposition or worldbuilding, Rajaneimi's approach is the opposite, with explanatory narration kept to a bare minimum that left critics wishing the book had an index or glossary. It's definitely a novel to come back to after some exposure to other, less sparse styles of science fiction.
