Percy Jackson & Rick Riordan Mythverse Reading Order

Rick Riordan's Percy Jackson universe spans five interconnected series, 20+ novels, and mythology from Greek, Roman, Egyptian, and Norse traditions. Whether you're starting fresh or trying to figure out how the spinoff series connect, this is your complete reading guide — with every book in every series, in the right order.

About the Riordan Mythverse

Rick Riordan created Percy Jackson in the early 2000s as a series of bedtime stories for his son Haley, who had been diagnosed with dyslexia and ADHD. The conceit — that these learning differences are signs of a demigod heritage — became one of the most beloved elements of a series already packed with wit, heart, and propulsive adventure. The first book, The Lightning Thief, was published in 2005 and became an immediate classic.


The original five-book Percy Jackson and the Olympians series was followed by four more complete series and several companion books, all set in the same mythologically-infused modern world. Greek mythology gives way to Roman, Egyptian, Norse, and beyond. Characters cross over between series. The whole enterprise — sometimes called the "Riordan Mythverse" or "Rick Riordan Presents" universe — is one of the most expansive young adult fantasy worlds in contemporary fiction.


Disney+ began adapting the original series in 2023, with a new series starring Walker Scobell as Percy that has been well-received by fans of the books for its faithfulness to the source material.

Reading Order for Adults New to Rick Riordan

Start with The Lightning Thief (Percy Jackson book 1) — no exceptions. Even if you're an adult reader who thinks the books look too young for you, start at the beginning. The original Percy Jackson series establishes the world, the characters, and the mythology that everything else builds on. Do not jump to a later series. The books read fast and the investment pays off enormously once you reach the later, more complex installments.

Section 1 — Start Here: Percy Jackson and the Olympians

5 books • Greek mythology • Ages 10+ • Fully complete

1
The Lightning Thief book cover
2005 Start Here

The Lightning Thief

Percy Jackson has always been different — dyslexic, ADHD, expelled from every school he's ever attended. On a class trip to a museum, his pre-algebra teacher transforms into a monster and tries to kill him. Percy learns he is the son of a Greek god, and is accused of stealing Zeus's master lightning bolt. The book that launched an era of mythology-based YA fantasy — funny, fast, and impossible to put down.

2
The Sea of Monsters book cover
2006

The Sea of Monsters

Camp Half-Blood is under attack — its magical borders have been poisoned. Percy and his friends must journey into the Sea of Monsters (the mythological equivalent of the Bermuda Triangle) to find the Golden Fleece. A confident, energetic second installment that expands the mythology and deepens the friendship at the heart of the series.

3
The Titan's Curse book cover
2007

The Titan's Curse

When the goddess Artemis is captured, a quest is launched to rescue her before the winter solstice. Percy and his friends face monsters, prophecies, and the growing threat of the Titan lord Kronos. The third book is where the series makes a significant tonal shift toward higher stakes and more genuine danger. One of the strongest entries in the original series.

4
The Battle of the Labyrinth book cover
2008

The Battle of the Labyrinth

Kronos's army is preparing an invasion — and they plan to use Daedalus's Labyrinth as a secret passage into Camp Half-Blood's defenses. Percy must navigate the shifting maze while facing the most personal challenges the series has presented yet. A propulsive penultimate chapter that sets the stage for the finale with tremendous skill.

5
The Last Olympian book cover
2009 Series Finale

The Last Olympian

All five books have been building to this: Kronos has risen, Olympus is under siege, and Percy leads an army of young demigods in a battle for New York City and the fate of the gods. The fifth book delivers a finale that satisfies every promise the series made, wrapping up story arcs and delivering emotional payoffs with craft and generosity. A genuinely great ending.

Section 2: The Heroes of Olympus

5 books • Greek + Roman mythology • Read after Percy Jackson • Fully complete

1
The Lost Hero book cover
2010

The Lost Hero

Three new demigods — Jason, Piper, and Leo — begin at Camp Half-Blood with no memory of how they got there. A new threat is rising and Percy Jackson is mysteriously missing. The first Heroes of Olympus book introduces the Roman Camp Jupiter and expands the mythology significantly, setting up a larger, more complex arc.

2
The Son of Neptune book cover
2011

The Son of Neptune

Percy Jackson wakes up at Camp Jupiter with no memory of his past. He joins a quest to free Death and stop the giant Alcyoneus from destroying Alaska. A triumphant return for the series' original hero — told from Percy's perspective again after the new characters of book one, and deeply satisfying for fans who missed him.

3
The Mark of Athena book cover
2012

The Mark of Athena

The seven demigods of the Great Prophecy are finally together, sailing toward Rome aboard the Argo II. Annabeth follows the Mark of Athena on a solo quest that dates back to ancient times, while everyone else tries to prevent a war between the Greek and Roman camps. Ends on one of the most agonizing cliffhangers in the entire Riordan Mythverse.

4
The House of Hades book cover
2013

The House of Hades

Percy and Annabeth must survive Tartarus — the deepest pit of the Underworld — while their friends race to close the Doors of Death from the other side. The fourth Heroes of Olympus book is the darkest and most emotionally harrowing in the entire Riordan Mythverse, featuring some of the finest writing Riordan has ever done. Essential.

5
The Blood of Olympus book cover
2014 Series Finale

The Blood of Olympus

The seven demigods face Gaea in the final battle to prevent the earth goddess from destroying Olympus. The conclusion to the Heroes of Olympus arc — sprawling, action-packed, and deeply satisfying for readers who have followed these characters across ten books. Completes one of the most ambitious multi-series arcs in YA fantasy.

Section 3: The Trials of Apollo

5 books • Greek mythology + Apollo as narrator • Read after Heroes of Olympus • Fully complete

1
The Hidden Oracle book cover
2016

The Hidden Oracle

Zeus has punished Apollo by turning him into a mortal teenager named Lester. Powerless, acne-prone, and deeply undignified, Apollo must earn back his divinity by completing a series of trials. Narrated in first person by Apollo himself — a brilliant comedic conceit — the Trials of Apollo series is funnier and more self-aware than its predecessors while still delivering genuine stakes.

2
The Dark Prophecy book cover
2017

The Dark Prophecy

Apollo and Meg travel to Indianapolis, where the Roman emperor Commodus — now an immortal Triumvirate lord — controls the city. Apollo must free the Oracle of Trophonius and survive increasingly dangerous opponents while learning what it means to be truly responsible for others. The second Trials of Apollo book raises the emotional stakes considerably.

3
The Burning Maze book cover
2018

The Burning Maze

Apollo and his companions navigate the Labyrinth in Southern California, controlled by the cruelest of the emperors — Caligula. The third book features the most devastating character loss in the Trials of Apollo series and marks the point where longtime Riordan readers fully understand this is a series willing to go darker places than its predecessors.

4
The Tyrant's Tomb book cover
2019

The Tyrant's Tomb

Apollo arrives at Camp Jupiter to face Tarquin — an undead Roman emperor who threatens to destroy New Rome. The fourth installment delivers the series' best battle sequence and begins the convergence of storylines that will culminate in the finale. An emotionally hefty and satisfying penultimate chapter.

5
The Tower of Nero book cover
2020 Series Finale

The Tower of Nero

Apollo — still mortal, still occasionally embarrassing — must defeat Nero and face Python at the Oracle of Delphi to become a god again. The conclusion to the Trials of Apollo series wraps up fifteen books' worth of mythology and character development with warmth, humor, and genuine emotional resonance. An extraordinary cap to an extraordinary run of books.

Section 4: Other Riordan Mythverse Series

These can be read alongside the main series or after — they are set in the same world but follow separate casts.

Egyptian Mythology
The Kane Chronicles (3 books)

Siblings Carter and Sadie Kane discover they are descendants of ancient Egyptian magicians and must stop the chaos god Set from destroying North America. Set in the same world but a separate magical tradition. All 3 books complete: The Red Pyramid, The Throne of Fire, The Serpent's Shadow.

Norse Mythology
Magnus Chase and the Gods of Asgard (3 books)

Magnus Chase — cousin of Annabeth from Percy Jackson — dies in Boston and wakes in Valhalla to face Norse gods, giants, and the approach of Ragnarok. A strong series with some of Riordan's best humor and most inclusive representation. All 3 books complete: The Sword of Summer, The Hammer of Thor, The Ship of the Dead.

Percy Jackson Returns
The Chalice of the Gods (2023)

A standalone novel set after The Tower of Nero, following Percy Jackson as he applies to college — with the gods demanding three impossible quests first. A warm, funny return to the original hero. A second Percy Jackson standalone, Wrath of the Triple Goddess, was published in 2024.

Percy Jackson on Disney+

The Disney+ adaptation of Percy Jackson and the Olympians premiered in December 2023, starring Walker Scobell as Percy, Leah Sava Jeffries as Annabeth, and Aryan Simhadri as Grover.

Percy Jackson FAQ

How many Percy Jackson books are there?

The original Percy Jackson and the Olympians series is 5 books. Rick Riordan has written 4 additional series set in the same universe: The Heroes of Olympus (5 books), The Trials of Apollo (5 books), The Kane Chronicles (3 books), and Magnus Chase and the Gods of Asgard (3 books). Plus several standalone novels and companion books. All of the above series are complete.

Do the Percy Jackson series need to be read in order?

Yes — start with the original Percy Jackson and the Olympians (books 1–5) before attempting any other series. The Heroes of Olympus and Trials of Apollo directly continue storylines from the original series. The Kane Chronicles and Magnus Chase can technically be read independently, but both have crossover elements that are more rewarding if you've read Percy Jackson first.

Are the Percy Jackson books good for adults?

Absolutely. The books are classified as middle grade and YA, but they are fast, funny, and emotionally rich in ways that work for readers of any age. Many adults discover the series and read all 15+ books in a matter of weeks. The Trials of Apollo series in particular handles themes of redemption, mortality, and accountability in ways that resonate deeply with adult readers.

Is the Percy Jackson TV show on Disney+ good?

The Disney+ series (2023–) has been well-received by fans of the books for being substantially more faithful to the source material than the 2010 film. Rick Riordan's direct involvement as a producer has reassured fans. Season 1 adapts The Lightning Thief across 8 episodes. If you loved the books, the show is worth watching — but read the books first.

Where does The Chalice of the Gods fit in the reading order?

The Chalice of the Gods (2023) is a standalone novel set after The Tower of Nero (the end of Trials of Apollo). It follows Percy Jackson applying to college. Read it after completing the full Trials of Apollo series for maximum context and emotional payoff. Wrath of the Triple Goddess (2024) follows the same format.
