The Percy Jackson series is a 21st-century take on Greek mythology, focusing on Percy Jackson and his fellow demigod friends at Camp Half-Blood.
All of the demigods have ADHD and dyslexia, with Rick Riordan wanting to write a series that his son could relate to.
Due to that, he published the first book: Percy Jackson and The Lightning Thief, in 2005. Since then, there have been numerous sequels and two film adaptations starring Logan Lerman as Percy.
As of 2022, there is also a Disney+ TV based on Percy Jackson and the Olympians.
But how many books can an entire TV series be based on it? Well, officially, the Percy Jackson series contains only five novels, but they have also been adapted into graphic novels.
Along with this, there are four companion books and only part of the Camp Half-Blood Chronicles. Following Percy Jackson’s stories are the five novels in The Heroes of Olympus and five more in The Trials of Apollo series.
These books are set in the same universe as Riordan’s Kane Chronicles and Magnus Chase series.
Percy Jackson And The Olympians
Percy Jackson and the Olympians is the first part of the Half-Blood Chronicles. It features Percy as the protagonist as he discovers he is the demigod son of the Greek God Poseidon. There are five books set in this series:
The Lightning Thief
The Lightning Thief was first published in 2005. In the first book, Percy goes on a quest to save his mother and discovers that his birth father is the Greek god of the sea: Poseidon.
Joining him on this quest is his best friend, a satyr called Grover Underwood, and the daughter of Athena: Annabeth Chase. Together, they embark on a trek to the Underworld to discover who stole Zeus’s lightning bolt before a war erupts.
The Lightning Thief has also been adapted into a graphic novel and got a film adaptation in 2010.
The Sea of Monsters
The Sea of Monsters is the second novel in the series and was published in 2006. Taking place a year after The Lightning Thief, Percy heads back to Camp Half-Blood for the summer with Annabeth and his cyclops half-brother: Tyson.
Together, they go on a quest to save Grover, who has left on his own journey to find the missing Greek god: Pan.
While they’re also there to save Grover, they’re on another quest, along with Clarisse, the daughter of Ares, to find the Golden Fleece to save Camp Half-Blood, which has been under attack.
The Sea of Monsters has also been adapted into a graphic novel and was adapted into a film in 2013.
The Titan’s Curse
The Titan’s Curse is the third novel in the series and was released in 2007. Taking place six months after The Sea of Monsters, Percy meets Grover with Annabeth and Thalia Grace, the daughter of Zeus, to find two demigods at an Academy.
While rescuing them, Annabeth is kidnapped, and they join the Hunters of Artemis to save her. During this book, a Great Prophecy is revealed, and a child of Zeus, Poseidon, or Hades will bring about the destruction of the Gods and help Kronos defeat them.
The Titan’s Curse also has a graphic novel adaptation.
The Battle Of The Labyrinth
The Battle of the Labyrinth is the fourth book in the series and was published in 2008. Set a few months after The Titan’s Curse, Percy attends an orientation day at his new high school.
