PERCY JACKSON & THE OLYMPIANS (Core Series)

Recommended Age: 9-12 | Reading Level: Middle Grade (4-6)

This is where everyone starts. Five books following Percy Jackson as he discovers he’s the son of Poseidon and learns to navigate a world where Greek gods are real and live in modern America.

1. The Lightning Thief by Rick Riordan (2005)

KidsBookCheck Score: 66.8/100 (Kid: 74, Parent: 56, Tension: 68)

• What happens: Percy discovers he’s a demigod when monsters attack. He’s accused of stealing Zeus’s lightning bolt and must find it to prevent a war between the gods.

• Content notes: Violence in combat scenes, but nothing graphic. Age-appropriate for 9+.

2. The Sea of Monsters (2006)

• What happens: Percy and his friends sail on a ship to find the Golden Fleece to save a friend from a curse.
• Why read it: Introduces Annabeth’s backstory and deepens world-building. Percy’s confidence grows.

THE KANE CHRONICLES (Egyptian Mythology Series)

Recommended Age: 10-13 | Reading Level: Middle Grade (5-6)

Three books set in the same world but separate from Percy Jackson. Different mythology (Egyptian instead of Greek). Can be read independently.

Recommended Order:

Note: These don’t overlap much with Percy Jackson books, though there are crossovers. You can read them simultaneously with the main series or separately. Many families read them after Olympians but before Heroes of Olympus.

MAGNUS CHASE AND THE GODS OF ASGARD (Norse Mythology Series)

Recommended Age: 10-13 | Reading Level: Middle Grade to Young Adult (5-7)

Three books featuring Norse mythology. Set in the same world as Percy Jackson and Kane Chronicles, but with minimal overlap.

Recommended Order:

1. The Sword of Summer
2. The Hammer of Thor
3. The Ship of the Dead

Note: These are great follow-ups to Percy Jackson. Same humor and adventure, different mythology. Best read after at least the Olympians series.

THE COMPLETE READING ORDER (What Most Parents Do)

Option 1: Chronological by Release (Most Popular) 1-5: Percy Jackson & the Olympians 6-10: Heroes of Olympus 11-15: Trials of Apollo

Then either:

• Kane Chronicles (1-3)
• Magnus Chase (1-3)

Option 2: Mythology Groups (If You Want Variety) Alternate between:

• Percy Jackson & Olympians
• Kane Chronicles (can read book 1 after Olympians book 2-3)
• Continue mixing

Then:

• Heroes of Olympus
• Magnus Chase
• Trials of Apollo

Option 3: Just Percy (If You Want to Stay Focused) Read only the Percy Jackson related books (Olympians + Heroes + Apollo). Skip Kane and Magnus. Perfectly fine—they’re bonus content.

FAQ: Percy Jackson Reading Order

Do I need to read all 15 books?

No. The core experience is the five Olympians books. Heroes of Olympus continues that story perfectly. Trials of Apollo is excellent but not essential. Kane Chronicles and Magnus Chase are bonus content in the same universe.

Many families read Olympians (1-5) and stop. Others read through Heroes of Olympus (1-10). Both are completely satisfying.

Which series is appropriate for my 9-year-old?

Start with The Lightning Thief. If they love it and want more, continue through the Olympians series. By book 3, the content gets slightly darker, so consider their maturity level. Most nine-year-olds who’ve read book 1-2 can handle book 3.

Can my child read Heroes of Olympus without finishing Olympians first?

Technically yes, but why would they? The Olympians series is better, and Heroes of Olympus pays off more if you understand the backstory. Read Olympians first.

Should we read Kane Chronicles and Magnus Chase?

Only if your child wants more mythology after finishing a series. They’re wonderful bonus content, but not required for the main Percy Jackson story. They can be read parallel to other series or saved for later.

How fast do kids usually read these?

Most readers finish a book in 1-3 weeks, depending on age and reading skill. So a full 15-book journey might take 6-9 months. Faster readers might do it in 3-4 months. This is a wonderful year-long reading project for many families.

Is the Rick Riordan Presents line important?

That’s a different initiative where Riordan publishes other authors’ mythology-based series. Beautiful books, but not required for understanding Percy Jackson. They can be read as bonus content.

Parent Tip: The Series Timeline

The books within each series should be read in order. But the timing of between series is flexible:

• Strict Order Needed: Olympians → Heroes of Olympus (Heroes depends on knowledge of Olympians)
• Flexible Timing: Kane Chronicles can begin after Olympians book 2-3
• Flexible Timing: Magnus Chase can begin after Olympians or Heroes books 1-2
• Flexible Timing: Trials of Apollo can begin after Heroes of Olympus
