A Song of Ice and Fire Series

By George R.R. Martin

The epic fantasy series spans two continents and follows more than twenty point-of-view characters vying for power in myriad ways. The characters move across the land like chess pieces, from north of the Wall to the desert sands of Dorne, across the sea to Essos, and into the grasslands of the Dothraki Sea.

With five books published and (hopefully) two more to come, this is a series that will immerse you not only in an expansive world but political intrigue, betrayal, vengeance, and more.


Red Rising

By Pierce Brown

More than a sprawling world, this series sweeps across the solar system. Once considered a Red—the lowest caste in society, destined for manual labor—Darrow infiltrates the Gold aristocracy, determined to break the chains of his people. 

The series is set in the distant future, featuring terraformed worlds. Each step of Darrow’s rebellion sweeps the reader through space, visiting far-off planets in his quest for freedom.

The Dark Tower

By Stephen King

Though the series is primarily set in Mid-World, in King’s The Dark Tower, every world is at stake. Roland and his crew are the only ones who can save defeat the Man in Black before he destroys the Dark Tower, which is the anchor point of all realities. We make our way across and between worlds, witnessing wonders and nightmares alike. 

With eight books and a short story, there’s plenty to experience. If you still want more of this epic world after finishing the series, you can find traces of it in King’s other novels. His expansive multiverse connects many of his classics in interesting and unexpected ways.

The Priory of the Orange Tree

The Priory of the Orange Tree

By Samantha Shannon

A sprawling fantasy set in a divided land, The Priory of the Orange Tree has so many aspects epic fantasy fans love: pirates, mages, assassins, and wyverns. The political intrigue is complex, the friendships are layered, and the romance is swoon-worthy. 

Told through various character perspectives, you’ll travel across kingdoms and seas, as unfathomable forces threaten to rise and threaten both the East and the West.

The Color of Magic

By Terry Pratchett

Discworld is more than just a story, it’s a universe of stories all built within and on top of each other, layers and layers of worlds and characters to discover and enjoy. With more than 40 books, six sub-series—each with myriad books, novellas, short stories, and companion novels—there is no shortage of adventure.

The series is full of laugh-out-loud writing and characters that feel like friends. If you’re looking for a world to spend inordinate amounts of time with, this is it.
