Honestly, I’ve asked this same question in bookshops and online forums more times than I can count — it trips people up because of how Rick Riordan split the world into multiple series. The second major Percy Jackson-era series is usually called 'The Heroes of Olympus', and it contains five main novels.
Those five books are, in order: 'The Lost Hero', 'The Son of Neptune', 'The Mark of Athena', 'The House of Hades', and 'The Blood of Olympus'. They were published across 2010–2014 and expand the cast dramatically while tying back to the original 'Percy Jackson & the Olympians' crew. If you’re collecting, there are also companion short-story books and anthologies like 'The Demigod Diaries' and later series such as 'The Trials of Apollo' that sit in the same universe, but the core second series itself is five books.
If you’re planning a re-read binge, I’d read the original five Percy Jackson books first, then dive into these five for the full emotional payoff — the callbacks land so much harder that way.

Man, I can't count how many times I've re-read 'Percy Jackson and the Olympians'! The series has five books in total, starting with 'The Lightning Thief' and wrapping up with 'The Last Olympian.' Each one just gets better, diving deeper into Percy's world and the Greek myths twisted into modern times. I still get chills remembering the Battle of Manhattan in the final book—Rick Riordan really nailed the epic conclusion.
What's cool is how the series set up the whole 'Riordanverse,' leading into 'Heroes of Olympus' and beyond. It's crazy to think how much these books shaped my love for mythology. I even started researching Greek gods because of them!

They're asking about the number of books to "complete" the series, and that depends on what you mean by completion. If you're talking about the original Percy Jackson & the Olympians pentalogy, that's five: 'The Lightning Thief', 'Sea of Monsters', 'Titan's Curse', 'Battle of the Labyrinth', and 'The Last Olympian'. That story about the Great Prophecy is fully wrapped up.
But Rick Riordan built a whole universe. After those five, there's the sequel series, The Heroes of Olympus, which is another five books. That one introduces Roman demigods and has a massive crossover finale. Some people consider the two series as one big ten-book saga for Percy's core journey, since the second series directly continues the world-ending stakes and finishes plot threads from the first.
Then you've got The Trials of Apollo, which is a direct sequel to HoO and is another five books. That's technically fifteen books if you follow the mainline Camp Half-Blood narrative from Percy's start to Apollo's conclusion. The most recent series, The Chalice of the Gods, is a new Percy-focused trilogy, with two books out so far. So for a truly 'complete' chronological experience of that world as it stands, you're looking at seventeen novels and counting.

which started it all, has a total of five books in the main 'Percy Jackson & the Olympians' series. They are 'The Lightning Thief', 'The Sea of Monsters', 'The Titan’s Curse', 'The Battle of the Labyrinth', and 'The Last Olympian'. Each book builds on the last, weaving Greek mythology into modern-day adventures in a way that feels fresh and exciting. Riordan’s humor and knack for relatable characters make these books a joy to read, whether you’re a kid or just young at heart.
Beyond the main series, Riordan expanded the universe with the 'Heroes of Olympus' series, which adds another five books, and the 'Trials of Apollo' series, which has five more. While these aren’t technically part of the original Percy Jackson lineup, they feature many of the same characters and continue their stories. There’s also a bunch of companion books and short stories that dive deeper into the world. It’s a massive, interconnected universe that’s perfect for anyone who loves mythology blended with contemporary settings. I still get nostalgic thinking about how these books got me hooked on reading as a kid.

The Percy Jackson series feels like an old friend to me—I’ve lost count of how many times I’ve reread it! The original 'Percy Jackson and the Olympians' series has five books: 'The Lightning Thief', 'Sea of Monsters', 'The Titan’s Curse', 'The Battle of the Labyrinth', and 'The Last Olympian'. But Riordan didn’t stop there. He expanded the universe with 'The Heroes of Olympus', another five-book sequel series, and then the 'Trials of Apollo' trilogy. There’s also the 'Kane Chronicles' and 'Magnus Chase' series, which are set in the same world but focus on Egyptian and Norse mythology, respectively.
If we’re strictly talking about Percy’s direct adventures, though, it’s those first five books that really define the core journey. Riordan’s spin-offs and crossovers add layers, but the heart of the story remains Percy’s growth from a confused kid to a hero who saves Olympus. The way Riordan blends modern humor with ancient myths still blows my mind—I’ve recommended these books to so many friends, and they always come back raving about them too.

I still get a little giddy every time someone asks about 'Percy Jackson & the Olympians' — it was such a gateway series for me. The original run has five books, plain and simple: 'The Lightning Thief', 'The Sea of Monsters', 'The Titan's Curse', 'The Battle of the Labyrinth', and 'The Last Olympian'. Those five carry Percy from discovery through a full-blown quest arc and a proper conclusion; they were deliberately compact and punchy, which is part of why the series hooked so many readers.
I first binged them during a rainy week, with a mug of tea and a sticky bookmark, and I was struck by how each installment escalates stakes and deepens friendships without overstaying its welcome. If you like pacing that keeps moving, this set is made for re-reads. Also, if you’re curious after finishing those five, there are follow-ups and companion series like 'The Heroes of Olympus' and shorter camp stories that expand the world, but they’re not part of the original five-book arc.
So yeah — count: five. If you want a reading tip, start with 'The Lightning Thief' and try to enjoy the surprise beats; even returning readers get little laughs and details they missed the first time. I still smile at the bus scene in chapter one every time."

The Percy Jackson series is one of those worlds I keep revisiting like an old friend. Rick Riordan crafted two main series: the original 'Percy Jackson & the Olympians' with five books, starting with 'The Lightning Thief,' and the sequel series 'The Heroes of Olympus,' which adds another five. That’s ten novels total if we’re counting just Percy’s core adventures. But if you dive deeper into Riordan’s universe, there’s also 'The Trials of Apollo,' where Percy pops up occasionally, plus standalone spin-offs like 'The Chalice of the Gods.' It’s wild how expansive this mythology has become—I’ve lost count of how many times I’ve reread 'The Battle of the Labyrinth,' my personal favorite.
Honestly, what makes these books so special isn’t just the quantity but how they grow with the readers. The first series feels middle-grade, while 'Heroes of Olympus' tackles heavier themes, almost like the characters age alongside you. And Riordan’s humor? Always on point. I still chuckle at Percy’s sarcastic narration, especially in 'The Mark of Athena.'
