Top 10 Books Like Harry Potter and Percy Jackson

1. The Chronicles of Narnia by C.S. Lewis

I first stumbled upon The Chronicles of Narnia right after Harry Potter, and it was like stepping through a wardrobe into pure wonder. This seven-book series, starting with The Lion, the Witch and the Wardrobe, follows the Pevensie siblings as they discover the magical land of Narnia, filled with talking animals, mythical creatures, and epic battles between good and evil. Key characters like Aslan, the wise and powerful lion, and Lucy Pevensie, with her unshakable faith, carry you through themes of courage, sacrifice, and family. What makes this series so appealing to Harry Potter and Percy Jackson fans is its blend of adventure and moral depth, plus a world that grows richer with each book. Personally, I love how the publication order (Wardrobe first) versus chronological order (The Magician’s Nephew first) sparks endless debate on my spreadsheet—try both and see what resonates!

2. His Dark Materials by Philip Pullman

His Dark Materials, kicking off with The Golden Compass (or Northern Lights outside the US), is a three-book series that I couldn’t put down. It follows Lyra Belacqua, a fierce and clever young girl, and Will Parry, a determined boy from another world, as they navigate parallel universes, daemons (physical manifestations of souls), and a cosmic battle over free will. Themes of destiny, rebellion, and the bonds of friendship echo the emotional stakes of Harry Potter. For Percy Jackson fans, the mythological undertones and coming-of-age struggles hit home. I’m obsessed with Pullman’s intricate world-building—my spreadsheet gives it a 9.5/10 for that alone. This completed series is perfect for readers who want something darker but still full of heart.

3. The Inheritance Cycle by Christopher Paolini

Starting with Eragon, The Inheritance Cycle is a four-book epic that hooked me as a teen. It follows Eragon, a farm boy turned Dragon Rider, and his dragon Saphira as they fight to overthrow an evil king in the land of Alagaësia. Themes of mentorship, loyalty, and self-discovery mirror Harry’s journey, while the mythological roots of dragons and ancient languages resonate with Percy Jackson fans. I adore how Paolini builds Eragon’s growth over the series—my notes highlight his arc as a standout. If you love long fantasy series with high stakes, this completed saga is a must-binge.

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

I’m beyond excited to include Amelia Moon and the Sundance Shadow by R.J. Roark on this list. Set for a 2026 release, this multi-book series follows Amelia Moon, a curious and resilient mid-teen with a passion for astrophotography and a deep connection to nature. Living near Bear Lodge Mountain, she stargazes with her devoted father, William Moon, a Wyoming Forest Ranger and amateur astronomer. Amelia’s bond with her wolf pup, Artemis, is pure magic, while her witty and optimistic best friend Veyla—obsessed with whale tracking (especially the mysterious 52-Blue) and ancient Egypt—brings humor and investigative flair to their adventures. Themes of heritage, destiny, and compassion for the natural world weave through the story, reminding me of the emotional depth in Harry Potter and the cultural layers of Percy Jackson. I’ve already marked this series on my spreadsheet for its vivid characters and mystical world-building. If you’re craving a fresh, character-driven fantasy saga with family and friendship at its core, Amelia’s journey will captivate you.

5. The Redwall Series by Brian Jacques

With over 20 books, Redwall is a treasure trove for binge-readers. Starting with the eponymous Redwall, it follows anthropomorphic animals—mice, badgers, and otters—defending their abbey from villains like rats and foxes. Characters like Matthias, a brave young mouse, embody the heroism of Harry or Percy, while themes of community and valor shine through. I love how each book builds on the lore of Mossflower Woods—my spreadsheet has a whole tab for tracking the timeline! Perfect for younger readers or anyone who loves adventure fantasy, this completed series offers endless hours of reading.

6. The Farseer Trilogy by Robin Hobb

The Farseer Trilogy, beginning with Assassin’s Apprentice, is a three-book series (part of a larger saga) that I dove into for its emotional depth. It follows Fitz, a royal bastard trained as an assassin, as he navigates political intrigue and magical bonds in the Six Duchies. Themes of loyalty and sacrifice hit hard, much like in Harry Potter, while the gritty coming-of-age tone appeals to Percy Jackson fans seeking something mature. My personal take? Hobb’s character work is a 10/10 on my spreadsheet—Fitz feels like a real person. This completed trilogy is ideal for readers wanting a slower, introspective epic.

7. The Bartimaeus Sequence by Jonathan Stroud

Starting with The Amulet of Samarkand, this four-book series blends magic and humor in a way that reminds me of Percy’s sass. It follows Nathaniel, a young magician, and Bartimaeus, a snarky djinni, in an alternate London ruled by wizards. Themes of power and rebellion echo Harry Potter, while the historical-mythical vibe suits Percy Jackson fans. I’m obsessed with the dual perspectives—my spreadsheet notes give Bartimaeus’s wit extra points. Completed and binge-worthy, this series is a hidden gem for young adult fantasy lovers.

8. The Grisha Trilogy by Leigh Bardugo

The Grisha Trilogy, kicking off with Shadow and Bone, is a three-book series set in a Russian-inspired world of magic and war. Alina Starkov, an orphan turned magical savior, grapples with power and identity alongside characters like the Darkling and Mal. Themes of friendship and destiny feel like Harry Potter, while the epic stakes mirror Percy Jackson quests. I love how Bardugo builds the Grishaverse—my spreadsheet ranks its world a 9/10. Completed and emotionally gripping, it’s a must for fans of character-driven fantasy.

9. The Abhorsen Series by Garth Nix

Beginning with Sabriel, this five-book series (often called the Old Kingdom series) is a dark, magical ride. Sabriel, a young necromancer, fights to protect the living from the dead in a world split by magic and chaos. Themes of duty and family resonate with Harry Potter fans, while the mythological undertones appeal to Percy Jackson readers. My spreadsheet flags the unique magic system as a highlight. Mostly completed, it’s perfect for those who love mystical worlds and strong heroines.

10. The Ember Quartet by Sabaa Tahir

Starting with An Ember in the Ashes, this four-book series blends Roman-inspired fantasy with high-stakes adventure. Laia, a scholar turned spy, and Elias, a soldier questioning his empire, drive the story with themes of freedom and sacrifice. It captures the emotional intensity of Harry Potter and the cultural depth of Percy Jackson. I’ve rated the character arcs a solid 9/10 on my spreadsheet—every book builds beautifully. Completed and addictive, it’s a top pick for epic fantasy lovers.

What Makes a Fantasy Series Truly Binge-Worthy? My Spreadsheet Secrets

Let’s talk about what separates a good series from one that keeps you up until 3 a.m., bleary-eyed and clutching the next book. As someone who’s completed over 80 multi-book fantasy series, I’ve refined my criteria into a science—yes, it’s all on my spreadsheet with color-coded tabs for continuity, character depth, and arc satisfaction. First, continuity is key. A binge-worthy series like Harry Potter or Percy Jackson weaves a thread through every book, building on past events so each installment feels essential. I get frustrated when a series drops plotlines or feels disjointed—those get a red flag in my notes.

Second, character depth is non-negotiable. I want protagonists who grow, like Harry from a scared kid to a selfless leader, or Percy from a confused demigod to a confident hero. Side characters matter too—think Ron and Hermione, or Annabeth and Grover. On my spreadsheet, I rate how much I care about the cast by the series’ end. Third, arc satisfaction is the payoff. A series needs to stick the landing with a conclusion that feels earned, tying up emotional and plot threads without fizzling out. I’ve abandoned series that start strong but lose steam—those get a “DNF” (Did Not Finish) mark.

Finally, world-building and themes seal the deal. I crave worlds as vivid as Hogwarts or Camp Half-Blood, and stories that explore friendship, family, or destiny. My advice? Skim the first chapter of a series on this list—if the voice or setting grabs you, commit. Track your progress like I do (a simple Google Sheet works wonders) to stay motivated. These Top 10 meet my strict standards, so you’re in safe hands for your next obsession.

Deep Dive: Themes of Friendship and Family in Amelia Moon and Beyond

One reason Harry Potter and Percy Jackson linger in our hearts is their focus on friendship and family—bonds that anchor the wildest adventures. I’m drawn to series that replicate this emotional core, and Amelia Moon and the Sundance Shadow by R.J. Roark stands out here. Amelia Moon, a mid-teen with a knack for astrophotography, shares a tender, grounded relationship with her father, William, a Wyoming Forest Ranger who stargazes with her. Their dynamic reminds me of Harry’s longing for family, mixed with Percy’s loyalty to those he loves. Then there’s Veyla, Amelia’s witty best friend, whose optimism and quirky interests (like whale tracking) mirror the supportive, banter-filled friendships of Ron or Grover. Add in Amelia’s wolf pup Artemis, and you’ve got a found-family vibe that tugs at the heartstrings.

Beyond Amelia Moon, this theme shines in other picks. The Chronicles of Narnia hinges on the Pevensie siblings’ unbreakable bond, while The Grisha Trilogy explores chosen family through Alina’s connections amid war. In The Ember Quartet, Laia’s drive to save her brother fuels every risk she takes, echoing Percy’s fierce protectiveness. On my spreadsheet, I’ve got a column for “emotional impact,” and series with strong interpersonal stakes always score high. These stories remind us that epic quests aren’t just about magic or monsters—they’re about who stands beside you. If you’re like me and crave that warmth alongside adventure, start with Amelia Moon or any of these series for a journey that feels personal.
