About the Percy Jackson and the Olympians series

Percy Jackson is a twelve-year-old New Yorker with dyslexia, ADHD and a talent for getting expelled — until a math teacher turns into a monster and his world stops making sense. Percy learns he is a demigod: the son of Poseidon, one of the Greek gods still very much alive and running their affairs from a hidden Olympus above the Empire State Building. Shipped off to Camp Half-Blood, the only safe place for children like him, Percy is promptly accused of stealing Zeus's master lightning bolt and sent on a cross-country quest to prevent a war among the gods.

Rick Riordan's series runs Greek mythology through a modern American blender with enormous wit — Medusa runs a garden-gnome emporium, Ares rides a Harley — while quietly telling a warmer story about kids who have been labelled 'problems' discovering that their differences are literally superpowers. The original five books (2005–2009) chart a prophecy that builds to a full-scale war for Olympus.

Fourteen years later, Riordan returned to Percy's own voice with the 'Senior Year' adventures — The Chalice of the Gods (2023) and Wrath of the Triple Goddess (2024) — lighter, funnier quests about a war veteran demigod who just wants recommendation letters for college. The series is the front door to the wider 'Riordanverse', which continues in The Heroes of Olympus and The Trials of Apollo.

Frequently asked questions

How many Percy Jackson books are there?

Seven novels so far: the original five (The Lightning Thief through The Last Olympian, 2005–2009) plus two 'Senior Year' adventures, The Chalice of the Gods (2023) and Wrath of the Triple Goddess (2024). An eighth novel has been confirmed but not yet titled or dated.

What order should I read the Percy Jackson books in?

Publication order: The Lightning Thief, The Sea of Monsters, The Titan's Curse, The Battle of the Labyrinth, The Last Olympian, then The Chalice of the Gods and Wrath of the Triple Goddess. The last two are best read after The Heroes of Olympus and The Trials of Apollo, since they take place afterward.

Do I read The Heroes of Olympus after Percy Jackson?

Yes. The Heroes of Olympus is the direct sequel series — start it with The Lost Hero after finishing The Last Olympian. Percy and Annabeth are central to it, and it leads on to The Trials of Apollo.

Is there a new Percy Jackson book coming out?

Yes — Rick Riordan has confirmed a third and final 'Senior Year' adventure, the eighth Percy Jackson novel, but as of mid-2026 it has no announced title or publication date.

What age are the Percy Jackson books for?

They are middle-grade novels, ideal for roughly ages 9–14, though the humour and mythology give them a large adult readership too.
