Best Sci-Fi Books by Page Count (Short to Epic)

Loved

And my top three picks were Blind Sight by Peter Watts, where hard sci-fi meets cosmic horror in this first contact story, Spin by Robert Charles Wilson, a sense of wonder sci-fi book where one day all the stars disappear, and in first place, Project Hail Mary by Andy Weir, a Macgyver in Space type story with the perfect blend of hard sci-fi and humor.

Loved

It had this incredible ability to make me feel incredibly small in comparison to the sheer vastness of the universe and yet also managed to still have a profound and personal effect on me. Arthur C. Clark is one of my favorite writers and I think for me childhood's end is his best.

Loved

This series combines epic world building, beautiful pros, intense action scenes, interesting character development, as well as some hard-hitting philosophy. I think it's pretty much everything that you could want in a space opera series, and I can't wait for the seventh and final book, which is coming out this November.

Loved

My top three picks were June, the classic sci fantasy space opera from Frank Herbert, Iliam by Dan Simmons, where the Iliad takes place on Mars, and number one, Disquite Gods by Christopher Rockio, book six in the Sunator series, which is his sci fantasy sword and planet space opera.

My top three picks were Pandora's Star, the first book in the Commonwealth duology, a highly descripted space opera from Peter F. Hamilton, Demon in White, the third book in the Sunita series from Christopher Rockio.

Loved

The hard sci-fi book about virtual reality that blew my mind almost every single chapter. And while this might put some of you off, I think if you can stand even just a little bit of hard sci-fi, please give it a chance because the ideas in this book are just mind-boggling.

Loved

Andy Weird does a great job of upping the stakes, presenting problems, and then using maths and physics in order to try and solve those problems. This book also features some really fun and witty dialogue and some great character dynamics.

And my three top picks for these shorter sci-fi books are The Futurological Congress, the trippy and satirical book by Stannislov Lem, The End of Eternity, a sharp time travel story from Isaac Asimov, and More Than Human, a poetic and philosophical book by Theodore Sturgeon.
