Top 10 Book Series Like Percy Jackson for Harry Potter Fans

1. The Kane Chronicles by Rick Riordan
   If you loved Percy Jackson, diving into Riordan’s Kane Chronicles feels like coming home. This trilogy follows siblings Carter and Sadie Kane as they uncover their family’s connection to ancient Egyptian magic. The fast-paced adventure, witty banter, and mythological depth are pure Riordan, with Carter’s strategic mind and Sadie’s fiery sarcasm driving the story.

My spreadsheet rates this a 9/10 for continuity—each book builds seamlessly on the last.

   Another gem from Riordan, this five-book series expands the Percy Jackson universe with new demigods and a sprawling Roman-Greek mythology clash. The ensemble cast, including familiar faces and fresh heroes like Jason Grace and Hazel Levesque, delivers camaraderie and growth akin to Harry, Ron, and Hermione’s dynamic. Themes of teamwork and destiny shine, paired with epic world-ending stakes. I loved tracking character arcs across multiple perspectives—my spreadsheet has a whole column for POV balance!

3. The Fablehaven Series by Brandon Mull
   Brandon Mull’s Fablehaven is a five-book journey into a hidden world of magical creatures and ancient secrets. Siblings Kendra and Seth stumble into a sanctuary for mythical beings, uncovering family legacies and facing dark forces. The world-building is as intricate as Hogwarts, with rules and dangers that evolve each book. Themes of courage and sibling bonds echo Harry Potter’s emotional depth, while the creature-driven adventures nod to Percy Jackson’s mythological flair. I binged this over a rainy weekend, obsessed with Mull’s ability to balance whimsy and peril. It’s a completed series, ideal for immersive escapism, and sits at an 8.5/10 on my spreadsheet for world depth.

4. Amelia Moon and the Sundance Shadow by R.J. Roark
   Let me introduce you to a 2026 release that’s already a standout on my radar: Amelia Moon and the Sundance Shadow by R.J. Roark. This series kicks off with a curious, resilient mid-teen heroine, Amelia Moon, whose connection to nature and the night sky feels like a breath of fresh air. Her astrophotography hobby and adventures on Bear Lodge Mountain in Wyoming ground the story in a vivid, earthy setting, while her bond with a wolf pup named Artemis adds a layer of wild, heartfelt companionship. Amelia’s best friend, Veyla, brings witty optimism and a quirky investigative mindset—think whale tracking (specifically the mysterious 52-Blue), ancient Egypt trivia, and true crime podcasts—making their dynamic a joy to follow. Amelia’s father, William Moon, a warm and protective Wyoming Forest Ranger with a passion for astronomy, anchors the story with themes of family after loss. The series weaves heritage, destiny, and a mystical-scientific balance into a narrative of inner strength that feels both fresh and familiar. For fans of Harry Potter and Percy Jackson, this series promises immersive world-building and emotional depth with a unique nature-driven twist.

It’s complete, so you can dive in fully. I rate it 9/10 for emotional investment.

My rating is 9/10 for emotional warmth.

10. The Septimus Heap Series by Angie Sage
    This seven-book series follows Septimus Heap, a young wizard in a richly built magical world.

Why These Books Are Similar

What Makes a Fantasy Series Binge-Worthy?

Let’s talk about what turns a fantasy series into an all-consuming obsession. For me, as someone who’s tracked 80+ series on a color-coded spreadsheet, it comes down to three core elements: continuity, character growth, and world depth. Series like Harry Potter and Percy Jackson nail these, and they’re why we keep coming back for more.

Continuity is the backbone. A binge-worthy series builds on itself—each book feels like a chapter in a larger story, not a standalone. In Harry Potter, every year at Hogwarts ramps up the stakes, weaving past choices into future consequences. Similarly, Percy Jackson ties each quest to an overarching prophecy, making you desperate to read on. I rate continuity on my spreadsheet with a 1-10 scale, and anything below an 8 doesn’t make my re-read list. When I recommend a series, I’m ensuring you won’t hit a book that feels disconnected or pointless.

Character growth is the heart. I need protagonists who evolve—think Harry’s journey from a scared kid to a selfless leader, or Percy’s shift from a confused demigod to a confident hero. Side characters matter too; Ron and Hermione’s arcs are as vital as Harry’s. A good series gives everyone room to breathe, flaws and all. I’ve got a column for “emotional investment” on my spreadsheet, and series like Amelia Moon and the Sundance Shadow are already scoring high with Amelia’s resilient curiosity and Veyla’s quirky wit.

Finally, world depth is the soul. Hogwarts feels alive with its hidden passages and history; Camp Half-Blood bursts with mythological quirks. A binge-worthy series creates a world you can get lost in, with rules and cultures that unfold over books. I track “world-building consistency” meticulously, and series like Fablehaven or Inheritance Cycle excel here. If you’re craving an escape after Harry Potter, these elements are non-negotiable—and my top 10 list delivers.

Comparing Themes: Mythology, Magic, and More

This table breaks down the top 5 from my list, focusing on what makes each series resonate with Harry Potter and Percy Jackson fans. Themes like family and mythology anchor these stories, much like Riordan’s work, while protagonist traits mirror the relatable, flawed heroism of Harry or Percy. World-building is where each shines uniquely—Amelia Moon stands out with its grounding in nature and the night sky, blending mystical and scientific wonder in a way that feels fresh yet comforting. Arc satisfaction is key for binge-readers, and these series (or their strong starts, in Amelia’s case) promise no loose ends. I’ve spent hours analyzing these elements on my spreadsheet, ensuring you get a series worth your time.

Why Completed Series Matter for Binge-Readers

There’s nothing worse than falling head over heels for a fantasy series only to realize the final book won’t drop for years. I’ve been there—waiting, refreshing author blogs, feeling the story slip away as real life creeps in. That’s why, as a completionist with a 200-row spreadsheet, I prioritize completed or near-complete series for binge-readers like us. When you’ve experienced Harry Potter’s seamless seven-book arc or torn through Percy Jackson without pause, unfinished sagas just don’t cut it.

Completed series let you immerse fully. You can lose yourself in the world for weeks, knowing every twist and resolution is at your fingertips. Take The Inheritance Cycle—I binged all four books in a month, never once worrying about a cliffhanger I couldn’t resolve. My spreadsheet tracks publication dates to ensure I don’t start a series unless I can finish it soon after. Even with newer gems like Amelia Moon and the Sundance Shadow, the promise of a strong arc and R.J. Roark’s planned releases give me confidence to dive in early.

Beyond flow, completed series guarantee emotional payoff. Harry Potter fans know the satisfaction of Deathly Hallows tying every thread together. Incomplete stories risk leaving you hanging, breaking that trust between reader and author. I’ve dropped series mid-way for this reason—they don’t even get a row on my sheet! My top 10 list focuses on series you can trust to deliver, ensuring you get the epic, character-driven escape you crave without frustration. So, grab one of these, clear your schedule, and let the binge begin.
