Percy Jackson Books in Order

The original five (2005–2009)

The Lightning Thief, The Sea of Monsters, The Titan's Curse, The Battle of the Labyrinth and The Last Olympian tell one story over five summers: a prophecy about a child of the Big Three gods, a war brewing with the Titans, and a kid who'd rather be at the beach. Read them strictly in order. They are fast, funny and smarter about Greek myth than they let on — Riordan taught middle-school Latin and mythology for fifteen years and it shows on every page.

The Senior Year Adventures (2023–)

Fourteen years after The Last Olympian, Riordan came back to Percy's own voice. The Chalice of the Gods (2023) and Wrath of the Triple Goddess (2024) are shorter, lighter, funnier books about Percy trying to get into college — he needs three letters of recommendation from gods, and gods don't hand those out for free. They are set after the Heroes of Olympus series, so strictly speaking you should read that first, but they are written to work for anyone who's read the original five. A third Senior Year book is confirmed and in progress; no title or date yet.

Where Percy goes next — the wider Camp Half-Blood world

The Heroes of Olympus (five books, 2010–2014) is the true sequel series: it introduces a second, Roman camp and a new cast, with Percy and Annabeth back in the story from book two. The Trials of Apollo (five books, 2016–2020) follows the god Apollo, stripped of his powers and stuck in the body of a teenager, with Percy as a supporting player. The Nico di Angelo Adventures — The Sun and the Star (2023) and The Court of the Dead (2025), both co-written with Mark Oshiro — follow one of the series' most beloved side characters. The Kane Chronicles (Egyptian gods) and Magnus Chase (Norse gods) are separate series that cross over with Percy in a handful of short stories. And a new Camp Half-Blood series begins with The Wild Zone in September 2026.

The simplest path: original five → Heroes of Olympus → Trials of Apollo → Senior Year Adventures and the Nico books. Or read the five and the Senior Year books and stop there, perfectly happily.

The show vs. the books

Two Percy Jackson films came out in 2010 and 2013 and Riordan has been cheerfully vocal about how little he liked them — he has said he never watched them. The Disney+ series, which he co-created and writes for, is the adaptation fans waited for: one season per book, cast at the right ages, faithful to the plot and the jokes. Season one (The Lightning Thief) premiered December 2023, season two (The Sea of Monsters) in December 2025, and season three (The Titan's Curse) arrives in November 2026.
