Current Status: No New Series Announced
As of late 2025 and into 2026, there is no new Percy Jackson series announced by author Rick Riordan or his publishers for a separate, full series continuation beyond established projects. The main story arc concluded with The Tower of Nero (2023), and ongoing work focuses on related content, reissues, and other Riordaniverse properties. Below, we clarify the difference between new books and reissues, review confirmed upcoming releases, and explain how to track credible updates.

What Constitutes a New Series vs. Repackaging
A new series implies original story arcs, characters, and ongoing stakes guided by the same creative vision. Repackaging includes refreshed covers, slipcases, or activity content drawn from existing material. Understanding this distinction helps set expectations for narrative progression and purchase decisions.
Indicators of a Future Series
- Formal announcement from Rick Riordan via website, newsletter, or sanctioned publisher event
- ISBN registration with imprint and wide distribution dates
- Substantial preview content such as prologue chapters or annotated text
Common Triggers for Rumors
- Convention sketches or placeholder covers from artists
- Leaked lists or speculative retailer placeholders
- Discussion threads extrapolating from side characters
How Riordan Expands the Universe Without New Main Series
Riordan sustains the Percy Jackson world through controlled extensions that respect the original narrative while creating space for new formats. These include standalone novels set in the same continuity, myth anthology collaborations, and interactive choose-your-own-style adventures that do not alter core continuity.
Official Extensions and Spin-Offs
- Magnus Chase and the Gods of Asgard concluded in 2022; no continuation announced
- The Trials of Morrigan series completed in 2024
- Demigods and Guides activity books and educator resources
Where to Find Verified Updates
To avoid misinformation, rely on primary channels and major retailer preorder data. Announcements about a new Percy Jackson series would first appear on established platforms with verifiable ISBNs, release windows, and author or publisher confirmation.
Reliable Sources
- Rick Riordan official website (riordan.com) and newsletter
- Publisher catalog updates from Disney-Hyperion and Penguin Young Readers
- Major booksellers with preorder activation (Amazon, Barnes & Noble, Bookshop.org)
Summary and Practical Takeaways
There is currently no new Percy Jackson series in active development as of 2026. Existing projects focus on reissues, activity content, and complementary Riordaniverse properties. For any future series, expect transparent announcements, ISBN registration, and wide availability through standard channels. Monitoring primary author and publisher sources remains the most reliable approach for accurate, up-to-date information.
