It is pretty well know by those close to me that I love science fiction, and there's a good reason that I love it. Science fiction contains some of the best ideas that you, as a reader, will ever hear about. Here are my favorite sci-fi books of all time, ranked from a scale of low to high.
1. The Martian
This book is pretty good. It's a story about an astronaut who is stranded on Mars for an extended period of time. Like a futuristic shipwreck tale.
2. 1984
Also a great read. It's pretty short, so it's good for a rainy day.
3. Fahrenheit 451
This book might give you nightmares if you love to read. There's a great lesson to be learned in this book.
4. Shadow and Claw
This book is a great read if you like fantasy as well as sci-fi. It's very deep and it has a great main character. Plus, there's a second part...
5. Sword And Citadel
The thrilling conclusion to Shadow and Claw. This books is just as good as, if not better than, the previous one.
6. Hyperion
A story of an alien planet, this book is long, but it's filled with beautiful ideas and vivid descriptions. It's also the first book in a series.
7. Ilium
I read this book earlier this year, and I thoroughly enjoyed it. It's a tale of time travel, and ancient Greece, mixed with some Shakespeare.
8. Foundation
Also another great read. This book actually teaches the reader some interesting stuff about laws and robotics. Book one of the Foundation Trilogy.
9. The Time Machine
It's a story about a man who travels all throughout time. Not scientifically accurate at all, but it's fiction, and it's a genius work of literature.
10. Ender's Game
Although the author of this book causes a lot of controversy with his beliefs, it's still a great book. It taught me, personally, a lot about myself, and I will always remember it for that.
11. A Fire Upon The Deep
By far, my favorite book of all time, science-fiction or otherwise. This book is very complex, and is filled with a vast multitude of technical terms. Some of the concepts provided within still hold up to this day, scientifically. The author, Vernor Vinge, has never written a bad book, at least in my opinion.
