Camp Half-Blood Is Back: Rick Riordan Launches a Collaborative Percy Jackson Series
Direct question: do you remember the first time you read Percy Jackson? Not the movie (let's not go there). The book. That specific moment when you understood that the Greek gods had been there the whole time — in the Empire State Building, in the school hallways, in the potholes on the highway — and that a kid with ADHD and dyslexia could be, against all logic, the most powerful among them.
That feeling is coming back, with an unexpected twist.
Rick Riordan has announced a new series of four books set in the Percy Jackson universe, each co-written with a different author. The collaborators are Annabelle Oh, Kyle Lukoff, Jade Adia, and Pablo Cartaya — the latter a Cuban American author with a strong track record in English-language middle grade and YA. The first volume, The Wild Zone, co-written with Oh, arrives September 29, 2026 from Random House Children's Books.
The premise is elegant in its simplicity: what was happening at Camp Half-Blood while Percy, Annabeth, and Grover were absent? Between the first and second novels of the original series, there is a gap. A gap that, it turns out, was full of bloodthirsty monsters, novice demigods, and forbidden territories. The Wild Zone follows five new characters in one of those territories.
What is genuinely interesting about this structural decision is that instead of writing Another Riordan Book™ solo — which would have sold millions regardless — he has chosen to build something choral. Each co-author brings their own references, their own reading community, their own ways of naming the world. It is, if you want to get slightly Borgesian about it, a library where each book is also the promise of another book by another voice.
Will it work? Nobody knows yet. But it is an energizing bet. Meanwhile, meet or revisit Rick Riordan with Percy Jackson y el cáliz de los dioses or La marca de Atenea from the Heroes of Olympus series.
