I'm the first to admit it took me some time to get into science fiction. As a kid, I fell asleep to my mom reading me the Lord of the Rings trilogy, and I graduated to C.S. Lewis once I could take over from there. But even though I spent hours trying to push through the back of my parents' closet and trying on every ring in mom's jewelry box in the hopes that one would turn me invisible, I always considered sci-fi the realm of the sweaty boys gathered in the living room with my brother.

But now that I'm older and wiser, I've completely changed my tune. The best sci-fi books aren't obtuse and inaccessible like I once thought. They're not written in some other language that relegates them to the math and science-brained. On the contrary, sci-fi's rich world-building, imaginative plot lines and deeply human thematic elements bring other worlds right down to Earth. We've rounded up the science fiction heavy-hitters that have made a real impact on the genre, have changed the literary world for the better or have just burst onto the scene with a comet-sized splash. Whether you're into near-future dystopias that imagine what the next hundred years might look like or prefer to send your brain to a galaxy far, far away, you'll have a wild ride on one of these fantastic sci-fi journey.

When Mary Shelley wrote Frankenstein in 1816, she didn't set out to create a cultural touchstone that would spin out into an entire genre. But that's exactly what she did. You probably think you know the story of Dr. Victor Frankenstein and his captivating creation but if you haven't actually read it, you owe it to yourself to crack open the granddaddy of sci-fi.

If you loved Station Eleven, you'll devour this dystopian novel that's as much about time travel as what happens when we lose sight of what's truly important. It hurtles from a plague-ravaged earth to colonies on the moon, from 1912 to the near future in a triumph that cements the author in the canon for good.

Ace The Dune Saga by Frank Herbert

The Dune Saga by Frank Herbert

I first read Dune as a teenager after my uncle passed me his dog-eared copy, and the far-future plant of Arrakis, where spice reigns supreme, immediately captured my imagination. Not only does Dune lay the foundation for such greats as Star Wars, Star Trek and futuristic space fiction as we know it. It's also a deeply original examination of religion, industrialization and the environment, class and society as a whole.
