The 23 best science fiction books:

Classic Science Fiction

An incredible staple of the science fiction genre

Book cover for "Dune" by Frank Herbert

“Dune” by Frank Herbert, available on Amazon and Bookshop from $9.49

Set in a futuristic world where the only thing of value is a drug used to extend life and assist in space travel, “Dune” tells the story of Paul, the heir in a noble family who is destined to rule a desolate planet. As the drug can only be mined on Paul’s planet, ruling a dangerous land fractured by betrayal thrusts him towards a destiny far different than the one he imagined. “Dune” is one of the bestselling science fiction novels of all time, one from which many tropes and concepts in the genre bloomed since its original publication in 1965.

A 1953 science fiction classic about a book-burning dystopia

Book cover for "Fahrenheit 451" by Ray Bradbury

“Fahrenheit 451” by Ray Bradbury, available on Amazon and Bookshop from $8.29

In this dystopian sci-fi, “firemen” set fire to homes containing books, which are now illegal. The story follows Guy Montag, a fireman who, after a series of peculiar interactions and events, begins to question the fabric of a society where knowledge and questioning information is outlawed. This classic has been studied and revered as a literary criticism of mass media, censorship, and conformity. It is extremely thought-provoking, and its messages are still as relevant today as they were in 1953.

A dinosaur utopia-turned-dystopia

Book cover for "Jurassic Park" by Michael Crichton

“Jurassic Park” by Michael Crichton, available on Amazon and Bookshop from $5.14

Though the movie franchise is more publicized than its 1995 source material, “Jurassic Park” is a techno-thriller literary apocalypse that shouldn’t be missed. When scientists develop technology to recover and clone long-extinct dinosaurs, they create an irresistible zoo-like attraction where people from around the world can watch real, living dinosaurs roam. But when an incoming storm threatens the security of the exhibit, everything quickly goes wrong. The book is darker than the movie, with stark differences in characters and their effects on the plot, such as John Hammond, who is far more egotistical and borderline evil in the book.

A new dystopian sci-fi work reminiscent of “The Handmaid’s Tale”

Science Fiction Thrillers

A science fiction story of colliding realities

Book cover for "Recursion" by Blake Crouch

“Recursion” by Blake Crouch, available on Amazon and Bookshop from $12.15

This is personally my all-time favorite science fiction novel. The story was mind-blowing and pacing was impeccable. In this novel, a technology has been created that not only preserves memories, but can transport people back to their most precious or emotional moments. This means people can enter a parallel universe where they play the winning lotto numbers, save their spouse from a car accident, or even stop 9/11. But when the alternate timelines begin to converge with the present, the forces of reality threaten to collapse.

A science fiction thriller about a stranded astronaut

Book cover for "The Martian" by Andy Weir

“The Martian” by Andy Weir, available on Amazon and Bookshop from $6.49

Though Andy Weir continues to release amazing science fiction space novels, “The Martian” is a fan favorite. Though just six days ago Mark was one of the first people to walk on Mars, his story quickly changed when a dust storm that nearly killed him forced his crew to evacuate, presuming him dead. Mark is abandoned with no way to contact Earth or his crew, and must rely entirely on his ingenuity and intelligence to survive against impossible odds in the hopes a rescue team may return.

A sci-fi love story

Book cover for "This Is How You Lose The Time War" by Amal El-Mohtar and Max Gladstone

“The Murderbot Diaries” takes place in a corporate-dominated future where all space travel must be accompanied by androids. But in a society where contracts are awarded to the lowest bidder, the androids are faulty — one self-aware unit has hacked its own system and refers to itself as “Murderbot”. Murderbot wants to be alone and explore its newfound cognitivity by binge-watching soap operas, but when a nearby mission goes dark, Murderbot and its assigned scientists must set out to save the others.

A new science fiction novel from the author of “Eragon”

Book cover for "To Sleep in a Sea of Stars" by Christopher Paolini
