Introduction: Why Series Matter to Adult Readers
There’s something undeniably special about settling into a well-written book series as an adult. Unlike standalone novels, a series allows for intricate world-building, deeper character arcs, and a sense of continuity that mirrors our life journeys. Whether you crave sweeping epics, biting satire, or raw psychological drama, the right series can transform your evenings, expand your worldview, and become part of who you are.
If you’re an adult reader tired of shallow plots and cookie-cutter heroes, this curated list of the Top 10 Must-Read Book Series for Discerning Adult Readers will help you find stories worth your time—and your bookshelf.
How to Choose a Book Series That Resonates with You
Before you dive into this list, pause to reflect: What kind of stories captivate you most? Do you love morally grey characters? Are you drawn to historical intrigue or mind-bending sci-fi?
Here are three quick tips:
Reflect on your current mood. Sometimes you need escapism; other times, you crave gritty realism.
Consider exploring the author's background. Many authors weave their life experiences into their series—knowing this deepens your reading.
Sample a few pages. Read a chapter before committing. The right series hooks you immediately.
1. The Lord of the Rings by J.R.R. Tolkien
No adult reading list is complete without Tolkien’s legendary trilogy (and the extended tales in The Silmarillion). This epic isn’t just about elves and orcs—it’s about good vs. evil, friendship, power, sacrifice, and the cost of heroism.
Key Highlights of the Series
The world-building is rich and immersive.
Aragorn and Frodo, for example, are nuanced characters who grapple with fear and responsibility.
It is a masterclass in myth-making that has inspired generations.
While many first read it as teens, rereading Tolkien as an adult uncovers new layers: the moral undertones, the sense of loss, and the resilience in the face of despair.
2. A Song of Ice and Fire by George R.R. Martin
If you want complex politics, raw human motives, and dragons—this is your series. Martin’s masterpiece has redefined modern fantasy for adults.
Character Depth and Moral Ambiguity

Yes, it’s famously unfinished. But what’s here is enough to absorb you for months—or years.

Her writing is brutally direct yet lyrical. The tension between Lila and Lenù mirrors the paradoxes of love and envy, loyalty and betrayal. For adults, Ferrante’s work feels deeply familiar—and painfully real.
4. The Expanse Series by James S.A. Corey
If you love sci-fi with grounded human drama, The Expanse should top your list. This nine-book series delves into interplanetary politics, social hierarchies, and morally complex areas.

5. The Wolf Hall Trilogy by Hilary Mantel
Few historical series are as masterful as Mantel’s Booker Prize-winning Wolf Hall trilogy. Through the eyes of Thomas Cromwell, you’ll experience the cutthroat court of Henry VIII like never before.
Mantel’s Cromwell is neither hero nor villain but a man navigating shifting loyalties and brutal ambition. It’s historical fiction that feels shockingly contemporary.
6. The Broken Earth Trilogy by N.K. Jemisin
Jemisin's Hugo Award-winning trilogy is a unique blend of diversity, genre-bending, and stunning originality. Set in a world ravaged by climate catastrophe, it follows marginalized characters fighting oppressive systems.
Jemisin tackles race, power, and survival with raw honesty. If you want modern fantasy that respects your intellect, read this.
7. The Discworld Series by Terry Pratchett
Pratchett's Discworld is a masterful example of satire. Though it spans 40+ books, you can jump into various mini-arcs (like the City Watch or Death series).
Pratchett lampoons everything: politics, religion, and human folly. Yet beneath the wit is a warm, humane perspective that comforts as much as it critiques.
8. The Millennium Series by Stieg Larsson & David Lagercrantz
The Girl with the Dragon Tattoo introduced the world to Lisbeth Salander—an unforgettable hacker heroine with a haunted past. This Nordic noir series tackles cybercrime, corruption, and abuse of power.
It’s gritty, fast-paced, and unflinchingly adult.
9. The Outlander Series by Diana Gabaldon
