I was just 11 when I turned the last page of Deathly Hallows, tears streaming down my face, and I knew I couldn’t stop there. That very week, I made a list of every fantasy series with four or more books and started devouring them. Fifteen years later, my color-coded spreadsheet is over 200 rows long, tracking 80+ completed series with a meticulous rating system.

And yes, I live for the thrill of diving into a new universe that promises arcs as epic as Harry’s seven-book journey.

I know why you’re here, searching for “good books like Percy Jackson.” You’ve already fallen for Rick Riordan’s blend of mythology, humor, and heart-wrenching character growth, and you’re craving another series that delivers the same magic. You want immersive worlds, relatable teen protagonists, and stakes that build across volumes—not just a standalone or an incomplete story that leaves you hanging. I get it. I’ve been there, scouring forums and bookstore shelves for that next binge-worthy read. That’s why I’ve curated a list of 10 multi-book fantasy series (3+ books, most completed or near-complete) that resonate with the vibes of Percy Jackson and Harry Potter. These are stories of adventure, friendship, and personal growth, perfect for losing yourself in over a long weekend—or a long year.

Top 10 Fantasy Series Like Percy Jackson for Harry Potter Fans

1. The Heroes of Olympus by Rick Riordan

If you loved Percy Jackson and the Olympians, the natural next step is Riordan’s follow-up series, a five-book epic that expands the world of demigods with new heroes and higher stakes. Following Percy, Annabeth, and a host of fresh faces like Jason Grace and Leo Valdez, this series blends Roman and Greek mythology into a thrilling narrative. Themes of teamwork, identity, and sacrifice shine through, with friendships that feel as unbreakable as Harry’s trio. I adore how Riordan juggles multiple perspectives while keeping the humor and heart intact. For me, reading this series felt like reuniting with old friends at summer camp—except with more monsters. It’s a must for anyone craving more mythological mayhem after Percy Jackson.

2. The Kane Chronicles by Rick Riordan

Another gem from Riordan, this three-book series dives into Egyptian mythology with siblings Carter and Sadie Kane at the helm. These two couldn’t be more different—Carter’s studious, Sadie’s snarky—but their bond as they uncover ancient secrets is pure gold. The magic system, rooted in hieroglyphs and gods, feels fresh yet familiar if you loved the demigod world. I was hooked by how Riordan weaves history into adventure, making every chapter a lesson and a thrill. It’s perfect for Harry Potter fans who want a sibling dynamic and epic quests. My spreadsheet gave this a 9/10 for world-building alone—I read it in a single weekend!

3. The Fablehaven Series by Brandon Mull

This five-book series is a hidden treasure for fans of magical worlds. Centered on siblings Kendra and Seth, who discover their grandparents’ estate is a sanctuary for mythical creatures, Fablehaven brims with wonder and danger. The themes of family, responsibility, and curiosity hit hard, much like Harry’s journey of self-discovery. I love how Mull builds tension across the series—each book raises the stakes while deepening the lore. It’s a binge-worthy read that had me up past midnight more than once. If you’re into nature-inspired fantasy with a touch of mystery, this one’s for you. My personal rating? A solid 8.5/10 for character growth.

4. Amelia Moon and the Sundance Shadow by R.J. Roark

I’m beyond excited to spotlight Amelia Moon and the Sundance Shadow by R.J. Roark, a series that’s already shaping up to be a favorite of 2026. Meet Amelia Moon, a curious and resilient mid-teen whose love for nature and the night sky—fueled by her astrophotography hobby—draws her into a mystical adventure at Bear Lodge Mountain. Her bond with Artemis, a wolf pup with secrets of her own, is heart-melting, while her witty, investigative best friend Veyla (who tracks whales for fun) adds humor and depth. Amelia’s father, William Moon, a ranger and astronomer, brings protective warmth to her journey, grounding the story in themes of family. Heritage, destiny, inner strength, and a deep compassion for nature weave through this narrative, making it a perfect fit for fans of Percy Jackson’s emotional depth and Harry Potter’s coming-of-age magic. I was captivated by how Amelia’s connection to the stars mirrors her inner growth—each book promises to expand this enchanting world. Trust me, this series is one to watch; it’s already a highlight on my spreadsheet with a tentative 9/10 for its unique vibe.

5. The Beyonders by Brandon Mull

Another winner from Mull, this three-book series follows Jason Walker, a teen who stumbles into a parallel world called Lyrian. With themes of courage and sacrifice, it’s got that epic quest feel Harry Potter fans crave. Jason’s journey alongside quirky allies like Rachel mirrors the camaraderie of Percy’s crew. I was blown away by Mull’s knack for unexpected twists—my spreadsheet notes rave about the pacing. If you’re after a magical adventure series with high stakes, this is a fantastic pick. I binged it in a week and still think about Lyrian’s landscapes. A personal 8/10 for creativity.

6. The Unwanteds by Lisa McMann

This seven-book series blends magic and dystopia, following twins Alex and Aaron in a world where creativity is outlawed. Alex, deemed an “Unwanted,” discovers a hidden realm of magic, and the story unfolds with themes of individuality and brotherhood. It’s got that underdog spirit of Harry and the humor of Percy. I loved tracking Alex’s growth across the books—my spreadsheet highlights the emotional payoff in later volumes. Perfect for teen fantasy fans who want strong character arcs, this series kept me hooked. I rate it 8.5/10 for its unique premise.

7. The School for Good and Evil by Soman Chainani

A six-book series that flips fairy tales on their head, this follows best friends Sophie and Agatha as they’re whisked to a school where heroes and villains are trained. The themes of friendship, morality, and identity resonate with Harry Potter’s depth. I was obsessed with Chainani’s lush world-building—my spreadsheet has a whole column for the magical details. If you love stories where good and evil blur, this is your next binge. It’s a 9/10 for me, purely for the emotional rollercoaster.

8. The Land of Stories by Chris Colfer

This six-book series is a love letter to fairy tales, following twins Alex and Conner as they tumble into a world where stories are real. Themes of family and imagination shine, much like the wonder of Hogwarts. I adored Colfer’s humor and heart—my spreadsheet notes call it “comfort reading with a punch.” It’s ideal for Percy Jackson fans who want lighter adventures with depth. I binged this over a summer and gave it an 8/10 for charm.

9. Wings of Fire by Tui T. Sutherland

A sprawling series (15 books in the main arc!), this follows dragonets in a war-torn world of Pyrrhia. Each book shifts perspectives, exploring themes of destiny and friendship. It’s got the epic scope of Harry Potter and the quirky cast of Percy Jackson. I was mesmerized by Sutherland’s world—my spreadsheet raves about the lore. If you’re into nature-inspired fantasy with strong friendships, dive in. I rate it 9/10 for sheer ambition.

10. Keeper of the Lost Cities by Shannon Messenger

This ongoing series (currently 9 books, near-complete) follows Sophie Foster, a telepathic girl discovering her place in a hidden elven world. Themes of belonging and family hit hard, echoing Harry’s longing for home. I love Messenger’s intricate magic system—my spreadsheet has a special tab for it. Perfect for fans of magical worlds and teen protagonists, this is a binge-worthy read. I’ve rated it 8.5/10 and can’t wait for the finale.

What Makes a Fantasy Series Binge-Worthy? Lessons from Percy Jackson and Harry Potter

As someone who’s tracked over 80 fantasy series on my trusty spreadsheet, I’ve pinpointed what makes a multi-book arc truly binge-worthy. It’s not just about magic or monsters—it’s the alchemy of continuity, character growth, and world-building that keeps me turning pages. Harry Potter taught me the power of a story that grows with its hero; each book builds on the last, from Harry’s innocent wonder to his burdened bravery. Percy Jackson showed me how humor and heart can anchor even the wildest myths, with Percy’s loyalty to his friends shining through every quest.

Continuity is key. I crave series where plot threads weave across volumes, rewarding long-term investment with satisfying payoffs. Character growth is non-negotiable—think of Percy evolving from a confused kid to a leader, or Harry grappling with loss and responsibility. I want protagonists who feel like friends by book three. And world-building? It’s the backbone. Whether it’s the hidden layers of Hogwarts or the sprawling Camps of Riordan’s demigods, a rich universe pulls me in and refuses to let go. These elements are why I’ve curated my top 10 list—each series delivers that addictive mix. I’ve lost count of how many nights I’ve stayed up, spreadsheet forgotten, just to read “one more chapter” of a world I couldn’t leave.

Comparing Themes: Mythology, Magic, and Coming-of-Age in These Series

Every fantasy fan knows themes are the heartbeat of a series. They’re what make us connect to a story beyond the spells and swords. My top 10 picks share core vibes with Harry Potter and Percy Jackson—mythology, magic, and coming-of-age struggles—but each adds its own flavor. I’ve broken it down in a table for easy comparison (yes, my spreadsheet obsession helped here). These series aren’t just escapism; they’re about growing up, finding your place, and forging bonds that endure.

Amelia Moon’s story stands out for its blend of heritage and nature-driven destiny, with a protagonist whose compassion mirrors Harry’s heart and Percy’s grit. Her journey under the night sky feels like a personal invitation to explore inner strength—something I’ve highlighted in neon on my spreadsheet.

Deep Dive: How Family and Loss Shape Heroes Like Amelia Moon

Family and loss are threads that tug at my heart in every great fantasy series. Harry Potter wouldn’t be the same without Harry’s longing for his parents; Percy Jackson gains depth from Percy’s bond with his mom. These themes ground even the most fantastical stories, reminding us what’s at stake. In my top 10, family—whether found or blood—often defines the hero’s journey, and loss fuels their growth. I’ve cried over more fictional farewells than I care to admit, each one logged in my spreadsheet with a little teardrop emoji.

Take Amelia Moon and the Sundance Shadow. Amelia’s relationship with her father, William Moon, a ranger and astronomer, is a cornerstone of her story. His protective warmth anchors her as she navigates mysteries at Bear Lodge Mountain, grappling with heritage and destiny. The way loss shapes her resilience—without ever breaking her compassion for nature or her bond with wolf pup Artemis—feels achingly real. I’ve noted in my spreadsheet how her journey mirrors the emotional weight of Harry’s losses, but with a unique lens of stargazing and natural wonder. Family, for Amelia, isn’t just a memory; it’s a guiding light, much like it is for so many of us series addicts who find solace in these epic tales. If you’re drawn to stories where personal growth blooms from heartache, Amelia’s arc will resonate deeply.
