Breakdown by Series
Percy Jackson & the Olympians
The Percy Jackson & the Olympians series consists of five main novels, starting with The Lightning Thief and ending with The Last Olympian. This series is widely regarded as the foundation of Rick Riordan's modern fantasy universe and has sold millions of copies worldwide. It also includes companion books and graphic novel adaptations that expand the story beyond the original five novels.
Beyond the core five books, the Percy Jackson universe includes additional titles such as the Demigod Files and graphic novel adaptations published by Penguin Random House. These companion works are often counted separately in total book tallies but are considered part of the broader Percy Jackson series by fans and retailers.
Kane Chronicles, Magnus Chase, and Trials of Apollo
The Kane Chronicles trilogy follows siblings Sadie and Carter Kane and consists of three main novels, with additional short stories and companion guides expanding the universe. The Magnus Chase series also comprises three main novels, set in the Norse mythology-inspired world of Hotel Valhalla, and includes a short story collection. The Trials of Apollo is a five-book main series that reimagines the Greek god Apollo as a mortal teenager.
When combined, these three series add more than a dozen main novels to Rick Riordan's bibliography. The Trials of Apollo is the longest of the three, with five books already published and a planned conclusion. Each series has its own companion guides and short stories that are sometimes included in total counts, depending on the source.
