Percy Jackson has been fighting monsters, challenging gods, and saving the world for more than two decades, but Rick Riordan still isn’t finished with the son of Poseidon.
After bringing Percy, Annabeth, and Grover back together in The Chalice of the Gods and Wrath of the Triple Goddess, Riordan confirmed that one more book is planned in what has become known as the Percy Jackson Senior Year Adventures.
So, when is the next Percy Jackson book coming out?
The short answer is that Rick Riordan expects the third and final Senior Year Adventure to arrive no earlier than 2027, although an official release date and title have not yet been announced. Riordan has said the book is in progress, and in a later update said that the first draft had been completed, but he has been careful not to guarantee a 2027 publication date.
There is also another new book coming from the Percy Jackson universe much sooner. The Wild Zone, the first novel in the new Camp Half-Blood series, is scheduled to be released on September 29, 2026 in the United States and United Kingdom. That novel is not the sequel to Wrath of the Triple Goddess, but it will expand the world of Percy Jackson with new demigods and stories set at Camp Half-Blood.
Here is everything fans need to know about the next Percy Jackson book, its possible release date, the Senior Year storyline, and what Rick Riordan is working on next.
What Is the Next Percy Jackson Book?
The next book centered directly on Percy Jackson is expected to be the third Senior Year Adventure.
It will follow:
- The Chalice of the Gods
- Wrath of the Triple Goddess
- Untitled third Senior Year Adventure
The story began because Percy needs three recommendation letters from Greek gods before he can attend New Rome University. Naturally, getting recommendation letters from the Olympians is much more complicated than asking a teacher or guidance counselor.
In The Chalice of the Gods, Percy accepts his first quest and earns his first recommendation.
In Wrath of the Triple Goddess, Percy takes on another seemingly simple assignment involving the goddess Hecate, her supernatural pets, and a Halloween week that quickly gets out of control. By the end of these adventures, Percy is still working toward completing the requirements for college.
That leaves one more recommendation letter and one more adventure.
Rick Riordan has explicitly confirmed that he intends to finish the storyline with a third and final Senior Year book.
When Will the Next Percy Jackson Book Be Released?
The third Percy Jackson Senior Year Adventure is currently expected in 2027 at the earliest.
That date should still be treated as an estimate rather than an official release date.
Riordan previously told readers that he could not imagine the book being published before 2027 and described even that timeline as a best-case scenario. In another response to fans, he said the book’s first draft was finished and that it would most likely arrive in 2027, while stopping short of making a firm promise.
That distinction is important.
There is currently no confirmed publication day, month, final title, cover, or official synopsis for the third Senior Year Adventure.
Until Disney Publishing or Riordan announces those details, any specific 2027 release date appearing on book-tracking websites should be considered a placeholder rather than confirmation.
For now, fans should expect:
Expected release: 2027 or later
Official release date: Not announced
Title: Not announced
Author: Rick Riordan
Series: Percy Jackson and the Olympians / Senior Year Adventures
Status: In progress, with Riordan saying the first draft has been completed
Why Is the Third Senior Year Percy Jackson Book Taking Longer?
One major reason is that Rick Riordan has a lot happening in the Percy Jackson universe.
Riordan originally confirmed in November 2024 that he would write a third Senior Year Adventure, but warned that it would not arrive the following year because he was working on other projects, including another Nico di Angelo novel and television adaptations.
Those projects have continued to expand.
Riordan has been heavily involved with the Disney+ adaptation of Percy Jackson and the Olympians, while his literary universe has also grown through books featuring characters such as Nico di Angelo, Will Solace, and Hazel Levesque.
Most recently, Riordan announced an entirely new series of novels centered around Camp Half-Blood.
All of that means Percy hasn’t been forgotten. His next story simply has to compete with a very crowded schedule.
The good news is that Riordan has repeatedly reassured readers that the final Senior Year Adventure is still happening.
What Will Percy Jackson Book 8 Be About?
We don’t have an official synopsis yet, but the larger storyline gives us a pretty good idea of what has to happen.
Percy needs three recommendation letters from the gods to attend New Rome University.
The first two Senior Year books cover his attempts to earn the first two.
That means the third book should revolve around Percy’s final divine recommendation letter.
Who will give Percy his final quest remains one of the biggest unanswered questions.
The structure of the first two books suggests that another Olympian or powerful figure will approach Percy with a task that sounds manageable before inevitably turning into something dangerous, ridiculous, or both.
And Percy will almost certainly not be handling it alone.
Will Annabeth and Grover Be in the Next Percy Jackson Book?
Nothing should be treated as confirmed until an official synopsis is released, but it would be surprising if the classic trio were not central to the final Senior Year Adventure.
The Chalice of the Gods brought Percy, Annabeth, and Grover back together in a way that deliberately recalled the dynamic of the original series.
Wrath of the Triple Goddess continued that approach.
Riordan himself described these newer adventures as stories focused on the classic trio while Percy tries to acquire his required recommendation letters.
The Senior Year books have been much more intimate than world-ending stories such as The Last Olympian or The Blood of Olympus. Instead of another enormous prophecy threatening civilization, these novels have allowed fans to spend time with Percy and his closest friends again.
That will likely remain one of the biggest attractions of the third book.
Is the Next Percy Jackson Book the Final Percy Jackson Novel?
It will be the final book of the Senior Year Adventures, but that does not necessarily mean it will be the last story Rick Riordan ever writes involving Percy Jackson.
There is an important difference.
Riordan has specifically referred to the upcoming book as the third and final Senior Year Adventure.
That closes the current story about Percy trying to get into New Rome University.
But the wider Percy Jackson universe has continued expanding long after the original five-book series ended.
Percy has appeared in The Heroes of Olympus, companion stories, crossover adventures, and other books in Riordan’s mythology universe. There is therefore no reason to assume that finishing his senior year means Percy can never appear again.
For the moment, though, fans should view the upcoming book as the conclusion of this particular chapter of Percy’s life.
And considering the entire trilogy is about getting Percy into college, the ending could create a natural transition into a very different era for the character.
What Is The Wild Zone?
This is where things can get confusing for anyone searching for the “next Percy Jackson book.”
Before the third Senior Year Adventure arrives, Rick Riordan is launching another series set in the same universe.
The first novel is called The Wild Zone and is scheduled for publication on September 29, 2026 in the U.S. and UK.
It launches the new Camp Half-Blood series.
These books will explore previously untold adventures at the famous demigod training camp and feature a new group of heroes. The stories take place during the timeline of the original Percy Jackson series, beginning around the period between The Lightning Thief and The Sea of Monsters.
Riordan is working with different co-authors on the series, including Annabelle Oh, Kyle Lukoff, Jade Adia, and Pablo Cartaya.
The new series is planned as four books, with subsequent installments expected approximately every six months.
That makes The Wild Zone an important Percy Jackson universe release, even though it isn’t the Percy-centered sequel fans have been waiting for.
The Difference Between The Wild Zone and Percy Jackson Book 8
If you’re trying to figure out which book you need to read next, here’s the easiest way to think about it.
The Wild Zone is a new story set in the Percy Jackson universe and centered around Camp Half-Blood.
The untitled third Senior Year Adventure is the actual continuation of Percy’s story after Wrath of the Triple Goddess.
So readers specifically waiting to find out whether Percy earns his final college recommendation letter will need to wait for the Senior Year book.
Readers who simply want another adventure at Camp Half-Blood will have something new much sooner.
What Are the Percy Jackson Senior Year Adventures?
The Senior Year Adventures effectively revived the original Percy Jackson and the Olympians series years after The Last Olympian concluded its original story.
The books are:
The Chalice of the Gods
Published in 2023, The Chalice of the Gods reunited Percy, Annabeth, and Grover.
Percy’s goal seems almost laughably ordinary compared to defeating Kronos: he wants to go to college.
Unfortunately, New Rome University requires Percy to obtain three recommendation letters from the gods because he technically wasn’t supposed to exist in the first place.
His first opportunity comes from Ganymede, who needs Percy to recover his missing chalice.
Wrath of the Triple Goddess
The second Senior Year Adventure was published in 2024.
This time Percy needs another recommendation and agrees to help Hecate by watching her animals while the goddess is away.
Predictably, things go badly.
The result is another adventure featuring Percy, Annabeth, and Grover together.
Percy Jackson Senior Year Adventure #3
The third book will conclude the recommendation-letter storyline.
Its title and full plot have not yet been revealed.
Riordan has indicated that it is most likely a 2027 release, but fans should wait for an official publication announcement before marking a specific date on the calendar.
Why the Senior Year Books Matter
Part of what makes these books so interesting is how different Percy’s situation is compared to when readers originally met him in The Lightning Thief.
He has already saved Olympus.
He has fought Titans and Giants.
He has traveled through Tartarus.
He has survived prophecies that would have destroyed most demigods.
Now his biggest objective is graduating high school and getting into college.
That smaller scale is part of the appeal.
Fans who grew up alongside Percy are now getting to see him deal with the transition into adulthood, while younger readers can still enjoy the humor, monsters, mythology, and quests that made the original books successful.
It also gives Riordan an excuse to bring Percy, Annabeth, and Grover back together without immediately inventing another apocalypse.
Where Does Percy Go After High School?
Percy’s destination has already been established: New Rome University.
New Rome is connected to Camp Jupiter, the Roman demigod counterpart to Camp Half-Blood introduced more extensively in The Heroes of Olympus.
That creates some intriguing possibilities once the Senior Year Adventures end.
Percy and Annabeth entering college could potentially open an entirely new phase of stories.
Riordan has not announced a college-era Percy Jackson series, so fans shouldn’t assume that one is coming. But the setting leaves the door open for future adventures if Riordan ever decides to return to Percy at that stage of his life.
For now, Percy just needs to get that final recommendation.
Considering his history with the Greek gods, that’s probably going to be much harder than it sounds.
More Percy Jackson Books Are Coming
Even with a longer wait for Percy’s next solo adventure, this is one of the busiest periods the franchise has ever experienced.
The Court of the Dead, featuring Nico di Angelo, Will Solace, and Hazel Levesque, was released in September 2025.
The Wild Zone launches the new Camp Half-Blood series on September 29, 2026.
And the third Senior Year Adventure remains in development for a potential 2027 release.
At the same time, the Disney+ series is continuing to adapt the original novels, bringing another generation of viewers into the world Rick Riordan created.
For longtime fans, that means the Percy Jackson universe is far from finished.
When Will We Learn the Title of the Next Percy Jackson Book?
There has been no official title announcement for the third Senior Year Adventure yet.
Historically, major details such as a title, cover, synopsis, and publication date are revealed closer to release.
Once the publisher formally announces the book, fans should finally learn which god gives Percy his third quest or at least receive enough clues to start guessing.
Until that happens, any supposed titles circulating online should be treated as rumors unless they come directly from Rick Riordan or his publisher.
When Is the Next Percy Jackson Book Coming Out? Final Answer
If you’re waiting for Percy’s next main adventure after Wrath of the Triple Goddess, the current answer is 2027 at the earliest.
Rick Riordan has confirmed that the third and final Senior Year Adventure is happening and has said that the first draft is complete. However, he has not announced an official release date, title, cover, or synopsis, and 2027 has been described as a likely or best-case timeframe rather than a guarantee.
In the meantime, fans won’t have to go without new adventures from Camp Half-Blood.
The Wild Zone arrives September 29, 2026, launching a new series of stories set in the Percy Jackson universe.
The most important thing is that Percy’s story isn’t over.
He still needs one final recommendation letter.
And knowing Percy Jackson, getting it probably won’t be easy.
