Comparing And Ranking The Percy Jackson vs. Heroes Of Olympus Series // ft. Percy’s Sassy Sarcasm, Greeks vs. Romans, And Epic Battles

you thought the Percy Jackson posts were over?? you were WRONG hahahahaha I’ll never stop

Hey loves! Apparently I have nothing better to do than talk about Percy Jackson!

I mean, it’s quarantine time so like what else to do besides Percy Jackson? I wanted to reread the original series randomly for comfort, and then I decided what the heck and binged the Heroes of Olympus series, which I had never read before.

I read the entire two series, 10 books, in one week (well, 8 days anyways). I just flew through them and it was basically all I was doing for the week was reading these books so I was thinking about them a lot! But! I was also too lazy to write them full reviews, especially since by the time I stopped reading to write about them I was several books behind on reviewing.

But I was still thinking about the a lot!! They’re really good! I wrote a post of mini reviews for the PJO series, and then a post of mini reviews for the HOO series, and then I continued writing about all the differences and comparing and contrasting them stuck on the end of my HOO series reviews, but that part alone was longer that all 5 reviews together, and so I thought, hey, why not squeeze another post out of this?


(But also I ranked all 10 books at the bottom and there’s no spoilers in that so just jump to the bottom!!!!)

PJOPercy Jackson is the main character of his series, with Annabeth and Grover as secondary major characters, and then a huge supporting cast of other major and minor characters such as Tyson, Clarisse, Rachel, Luke, Sally, etc. We really get to know Percy spending five books in his head, and he really grows a lot throughout the story, which I loved. There’s definitely growth throughout the variety of other characters, although somewhat limited since we only see them through Percy’s perspective


HOO: Heroes of Olympus is more of a squad type book series, with a huge ensemble case of main characters. There’s the seven of the prophecy: Percy, Annabeth, Jason, Piper, Leo, Hazel, and Frank. Nico and Reyna aren’t part of the seven, but they’re also major characters with chapters from their perspective. It’s great getting to see so many characters, as most of them are all amazing in their own ways. However, this made us unable to spend too much time with any one of them, and it could be annoying having to spend so many pages with any individual character if I didn’t really like them and wanted to get back to the characters I did love! (Percy >>>> Annabeth >>>> Leo >>>>> anyone else sorry).

Verdict: Percy Jackson. But this is probably more of a personal thing; I can see why you would like Heroes of Olympus more.

PJO: This section literally exists in my post so I can fangirl about Percy because first person Percy POV is literally giving me life. I love his snark and sassy, sarcastic, sense of humor and jokes. Reading his perspective feels like talking with a funny friend! I feel like what made PJO really stand out to me was the charm and heart, and I feel like that’s all from Percy.

HOO: Sorry I’m biased but my biggest problem with the HOO series is probably I feel it’s lacking the spark and charm from PJO from Percy’s first person monologue! These were still really good books of course, but they just didn’t stand out like Percy! I did like seeing various things from different perspectives though; for example, it was cool to see both Greeks and Romans thinking about the same thing and seeing how they changed in their eyes! I was also so happy to finally get the perspective of beloved characters: mainly Annabeth and Nico from PJO! I also loved getting to see specific events from the perspectives of various characters, but I wished that I could see some events from different characters than we were given!! (we were robbed of a chance to see Percy fighting alongside Poseidon and Annabeth reconciling with Athena after finding the Parthenon in BOO)

Also my biggest complaint of HOO is the lack of Percy POV in Blood of Olympus… it started with him it should have ended with him…

Verdict: Percy Jackson. I’m so biased.

PJO: There were some seriously amazing battles in these books! The fight between Percy and Ares at the end of Lighting Thief was amazing! I loved the fight in the end of Titan’s Curse, and basically everything Percy did in Battle of the Labyrinth discovering the full extent of his powers and what he could do and summon was incredible!

HOO: There was so much incredible action, battles, and use of power in this series! I loved getting to see Percy of course, but I loved what all seven could do! From Piper’s charmspeak and cornucopia, to Frank turning into animals, to Hazel manipulating the mist, to, my absolute favorite, Percy and Jason, sons of Poseidon and Zeus, fighting together with the air and sea, these fights were seriously amazing! I have to give it to this series because I loved seeing all the incredible things all these different heroes could do, together and apart!

Verdict: Heroes of Olympus

asset 1


PJO: You can’t have a good series without a good villain, right? The villain of this series was amazing! Kronos gradually stirring, rising, coming to power, and confronting them in a fight over 4 years was incredible to watch. And Luke was one of the best written characters ever! At times it was so easy, even for Percy, to understand his motivation, and his backstory with Annabeth and Thalia showed him to really be a fully fleshed, three dimensional character. The struggle with a former friend turning to bad, yet Annabeth continuing to hope he wasn’t all bad, which even came to be true as he redeemed himself and was “the hero” from the prophecy in the end was so emotional and compelling and incredible.

HOO: Gaea is a seriously terrifying villain! How can you fight against the Earth itself? Unfortunately, it seems that it was really easy, as I thought that the ending of Blood of Olympus was super anticlimactic. I thought throughout the series, Gaea was really built up to be a good foe, and I was certainly terrified, but she literally woke up and was defeated in like two chapters at the end I was like ???? that’s it?? And since she wanted to basically destroy everything there really wasn’t the emotion from Luke’s villain, it felt more two dimensional good and bad.

Verdict: Percy Jackson

PJO: This is a middle grade series so there’s really minimal romance, and that’s just fine; it’s not at all the point of the story. That said, I’m Percabeth trash and was loving the buildup from them being kid friends who annoy each other to falling for each other. I love how clueless Percy is haha. And best underwater kiss of all time ❤

HOO: This is also technically middle grade but felt more YA in multiple ways, including that there was significantly more romance. There were so many Percabeth moments that made me so happyyyyy! Percy literally fell into Tartarus for Annabeth oaisjfkalsejdifoaosidfkld. There were other romances too, including Jason and Piper (pretty cute), Hazel and Frank (also cute, although she’s literally 13 so it felt a bit weird at 13 Percy didn’t even know what a girl was I swear), Leo and Calypso (so adorable it had the least time but was my fav after Percabeth!!!), and a hint of Nico and Will at the end (ahh I just want Nico to be happy he’s too precious gah).

Verdict: Heroes of Olympus, based on romance alone. But if you’re not interested in romance in a middle grade fantasy book, Percy Jackson

Overarching Story

PJO: Percy Jackson takes place over a little more than 4 years, with the Titans gradually rising to power, and Percy eventually coming head to head with Kronos based on a prophecy on his 16th birthday. This isn’t the main focus of the story though until the last book; the first four books have the Titans as the overarching background story, but the immediate concerns are other smaller goals: return Zeus’s master bolt, retrieve the Golden Fleece, rescue Artemis and Annabeth, stop Luke from using the Labyrinth. I liked the focus on these individual quests, each with its own prophecy and small group of people going on the quest, while fitting in to the Titan story.

HOO: Heroes of Olympus has the overarching story of stopping Gaea from awaking, which takes place over less than a year. The first two books had their own small quests, while the last three books felt like they were all three parts of the same one story, flying on the Argo II to the ancient land to stop Gaea, while also preventing war between the Greeks and Romans. I personally felt this less left room for development since it was so quick (less than a year), and the story felt less of a complex gradual buildup and more direct.

Verdict: Percy Jackson for me but I feel like this one is probably personal preference too.

World And Mythology

PJO: I loved the Greek mythology of Percy Jackson! It was super cool and interesting to see the world, the gods, the myths. The greek mythology was also fairly easy to understand, which was good.

HOO: This really expanded the world to more gods and monsters and myths, to contain both Greek and Roman mythology. It really made the world bigger and more complex and incredible. At times it could get a bit confusing though, especially wrapping my head around the one same god having both a different Greek and Roman aspect.

Verdict: Heroes of Olympus

asset 1


PJO: This has literally nothing to do with how objectively good the books are but I have to say that these books make me so nostalgic. I read the when I was 10, and these books were really a pivotal part of my childhood ❤

HOO: Sorry.

Verdict: Percy Jackson

Overall, I definitely preferred Percy Jackson over Heroes of Olympus. I would say that Heroes of Olympus is really good, but there are a lot of really good fantasy series, and this one really isn’t so memorable, and kind of fades into the many. Percy Jackson though, is so full of charm and heart, so wonderful and fresh and magical feeling, and it definitely goes in my list of all time favorite book series ❤

  1. Great post Kay!
    My favourite PJ is The Battle Of The Labyrinth too! And my fav HoO book is House of Hades btw.
    I personally liked the Heroes Of Olympus series better as it was a lot more mature and double dose of humor from Leo and Percy!

  2. I love both of these series so much! I agree that overall the Percy Jackson series is better but that could just be my nostalgia too!

    I found the Heroes of Olympus series harder to get into at first and almost gave up reading the first book but I am so glad I didn’t! I think I just wanted Percy ahaha!

  3. Hello! I am a big fan of Rick Riordan and I’m reading his books since I started college. I started with the five books – Percy Jackson series then the Heroes of Olympus series. I even read his other mythological novels and now I’m just done reading The Tyrants Tomb (Trials of Apollo series).

    Anyway, I’m just glad that there is someone here with the same interest! Keep writing!

  4. I also found Blood of Olympus to be super anti-climactic, and it super bothered me that we didn’t hear from Percy AT ALL. His narration is 100% why I fell in love with the series as well, and I think Rick Riordan has an excellent sense of humor. I also loved the chapter titles, which are sooooo funny.

  5. This post has just reminded me that I’m such a loser for not reading Percy Jackson already… I think I’ve read the first three. Luckily my brother has the complete collection, so I’ll be stealing from his bookshelves in the following days! Hope you’re well, and I loved this post so much x

  6. ooh this is such a great comparison between these two series! I agree with you on pretty much all of these, particularly the villains. Gaia is a scary villain, but we miss out on the emotions of the Luke dynamic and the shades of gray in Percy wondering if he should even be defending the Olympians since they kinda suck. It definitely feels more two dimensional in HOO. I love both of these series, but PJO will ALWAYS be the favorite for all of these reasons 🙂

  7. Haha this is such a great post and I bow down to you for being able to read the ten books in eight days (granted as a child each time a new HoO book came out I would spend the entire day reading it and finish it) maybe it’s because I started Percy Jackson late and HoO would release a new book each year but I definitely prefer HoO, I miss reading Rick Riordan books though I kinda stopped after the first Trials of Apollo book and never caught up but I really should!

  8. Awesome post, Kay! ❤ I think you really hit the nail on the head about why the narration in PJO is better than HoO! I love my baby Percy so much and his narration and inner monologue is what I live for (and would die for but that's beside the point). I adore these books so much, but I think I'll always gravitate towards the original series. Overall, I just preferred the story, characters, and villains more. I did love some of the battle sequences and world building int he hoO series. How Riordan interlaced Roman with Greek mythology was fantastic!

    1. Thanks! Yesss I really like the other characters, but it’s just not the same as listening to Percy’s amazing sarcastic sassiness ❤ Yeah, HOO was great and I'm glad I read it once, but PJO is next level I'll probably reread it many more times for Percyyy ❤


  9. Ahhh this is so so amazing Kay!!! I agree that I’m probably also pretty biased towards PJO and all, but both series are so amazing! Anyways, this was so fun to read!

  10. I personally prefer the HOO series to the PJO series. It brought a new depth and maturity and abilities to the table. Seeing all these young heroes come together in the mark of Athena was really amazing. I really enjoyed the relationships between all 7 demigods, and Leo definitely remains one of my favorite characters from the entire 10 books series. Personally the HOO book series are my favorite with the Mark of Athena and House of Hades coming at 1 & 2
