Rick Riordan

Hazel stands at a crossroads. She and the remaining crew of the Argo II could return home with the Athena Parthenos statue and try to stop Camp Half-Blood and Camp Jupiter from going to war. Or they could continue their quest to find the House of Hades, where they might be able to open the Doors of Death, rescue their friends Percy and Annabeth from Tartarus, and prevent monsters from being reincarnated in the mortal world. Whichever road they decide to take, they have to hurry, because time is running out. Gaea, the bloodthirsty Earth Mother, has set the date of August 1 for her rise to power.

Annabeth and Percy are overwhelmed. How will the two of them make it through Tartarus? Starving, thirsty, and in pain, they are barely able to stumble on in the dark and poisonous landscape that holds new horrors at every turn. They have no way of locating the Doors of Death. Even if they did, a legion of Gaea's strongest monsters guards the Doors on the Tartarus side. Annabeth and Percy can't exactly launch a frontal assault.

Despite the terrible odds, Hazel, Annabeth, Percy, and the other demigods of the prophecy know that there is only one choice: to attempt the impossible. Not just for themselves, but for everyone they love. Even though love can be the riskiest choice of all.

The Heroes of Olympus, Book 4

The House of Hades

At the conclusion of The Mark of Athena, Annabeth and Percy tumble into a pit leading straight to the Underworld. The other five demigods have to put aside their grief and follow Percy’s instructions to find the mortal side of the Doors of Death. If they can fight their way through the Gaea’s forces, and Percy and Annabeth can survive the House of Hades, then the Seven will be able to seal the Doors both sides and prevent the giants from raising Gaea. But, Leo wonders, if the Doors are sealed, how will Percy and Annabeth be able to escape?

They have no choice. If the demigods don’t succeed, Gaea’s armies will never die. They have no time. In about a month, the Romans will march on Camp Half-Blood. The stakes are higher than ever in this adventure that dives into the depths of Tartarus.

"Stupid rock gods!" Leo yelled from the helm. "That's the third time I've had to replace that mast! You think they grow on trees?"

Jessie!

Her voice caught on the word friend. Percy was a lot more than that. Even boyfriend really didn't cover it. They’d been through so much together, at this point Percy was part of her—a sometimes annoying part, sure, but definitely a part it she could not live without.

Yeah Percy don’t even try to understand it

He wondered if he'd done something to offend the guy.

"Oh, obviously," Reyna said. "Without you, I doubt Percy could find his way out of a paper bag." True," Annabeth agreed.

"No, Leo," Hazel said. "There's no way back." "But " "Hold my hand," she said. "On three." "But" "Three!" "What?"

If all monsters had to near that song about liking piña coladas and getting caught in the rain, no wonder they were in the mood for carnage when they reached the mortal world.

"You don't see the ghost?" Frank asked. "Ghost?" Nico asked.

Oh poor Leo don’t remind him his wound is to fresh

"Maybe because of this." Frank tapped his brochure. "Says here Malta was vwhere Calypso lived."

tiktok told me Jason will die so I’m sitting here waiting for something to hapoen

 he couldn't let his friend die for his sake. He could never live with the guilt.

"Im coming back for you, Calypso," he said to the night wind. "I swear it on the River Styx."

She grabbed his face and pulled him into a kiss, which effectively shut him up.

“But if it only shows up for guys you like "Don't push your luck, Leo Valdez," she said. "I still hate you "

So Percy was right they did not keep their promise 

She dug her fingers into the soil. H thought I would be released. I dared to hope... but I am still here."

I think I know where you are and I really don’t like it…

He staggered across the beach, wondering why there weren't any tourists or hotels or boats in sight. The island seemed perfect for a resort

Oh poor fucking nico that not the way to put someone

"I had a crush on Percy," Nico spat. That's the truth. That's the big secret."

Yeah you do so shut up he has it hard with his internal homophobia 

"Ive been to Tartarus and back," Nico snarled. "You don't SCare me" I scare you ver, very much. Face me. Be honest.

Nico didn't look convinced. In fact he looked like he was going to be sick. But he squared his shoulders and nodded. You're right. II'm not afraid ofa love god."

"We've arrived," Leo announced. "Time to Split. Frank groaned. "Can we leave Valdez in Croatia?"

Percy clenched his jaw. He didn't care how many curses he suffered. He had to keep these leathery old hags focused on him and protect Annabeth as long as he could. He yelled in fury and attacked them all.

The voice cackled maliciously. To curse you, of course! To destroy you a thousand times in the name of Mother ight! "Only a thousand times?" Percy murmured. "Oh, good... I thought we were in trouble."

No food, no water...basically no supplies at all. Yep. Off to a promising start.

Oh god I love their friendship. I’m really rooting for all of them. They’re all so precious. Reyna and Nico included.

This is so much more intense than the other Riordan books to me. I loved seeing more of Percy and Annabeth together and the detailed descriptions of Tartarus.

A couple things to talk about:

I LIKED that we got the perspective of ALL SEVEN from the Prophecy. But...
For some reason, I keep feeling like we haven't had Piper's perspective since the Lost Hero, but I JUST READ the Mark of Athena, and I'm pretty sure her perspective was in there, but I can't be sure. 
Anyways, I really FEEL like I haven't' seen anything in Piper's perspective since TLH, and her perspective only showed up once in this book, it was after page 300, and she talked about how much she had changed since TLH. I didn't really see it, but whatever. And then there was the whole controlling-machinery-with-the-power-of-love!!! That was REALLY cheesy.

And then there was the thing with Nico that we found out when he Jason visited Cupid... and it didn't surprise me, at all, because I accidentally spoiled myself on tumblr FIFTY PAGES BEFORE I GOT TO IT!!! I'm not going to say that the spoiler ruined the experience for me, i mean would have preferred to have been surprised, but I still liked the twist, I think it made a lot of sense, and it adds a lot of depth to his character.

Also, Bob. Like, omigod, Bob. My eyes actually watered while I was reading this book, and it was for Bob.

*When I say my eyes watered, that's like as close as I get to crying*

Overall, I really loved this book, dived straight into the next and last one. It'l be hard, saying goodbye.

"Say hello to the sun and stars for me."

while reading this series i've come to love every of the main characters and that's why the problems they've struggled with in this book made me especially emotional. they all had suffered so much which pained me and even made me glad that i don't have troubles like them. it also felt like every one of them had a moment in this book that forced them to mature. their bravery and the usual for this series breathtaking adventures amazed me and sucked me in. i'm anxious but at the same time really excited about what will happen next.

I can't believe how I was super amazed by this book! I love how the 7 demigods have developed! OH LEO! And of couse NICOOOOOO 🥰 this is my favorite book in the series so far! Absolutely awesome!

Annika Arguemore

I do not understand why people describe this book as dragging, because while I was reading it, it did not feel at all like that. Perhaps it's because I feel too at home in or with this series? Maybe by just simply hearing about my favorite demigods, it really makes me feel glad to know that they're still out there (albeit in another fictional dimension) taking on adventures? Perhaps it is this way.

I also felt that this book kind of just delayed the inevitable. This novel was a transition towards the real thing, but not the real deal itself, which is fine. We all need transitions as not to shock ourselves with what's about to happen.

           This is my favorite book out of all the books set within this beautiful world. Despite the terrible odds, Hazel, Annabeth, Percy, and the other demigods of the prophecy know that there is only one choice: to attempt the impossible. Not just for themselves, but for everyone they love. Even though love can be the riskiest choice of all. In one aspect, this book is a delightful yet stressful one, which resulted in most of my reading time spent trying not to freak out at the possibility that one of the seven might die. With Annabeth and Percy in Tartarus, the remaining group is attacked left and right. This book did not have a peaceful moment until the end, but even the ending doesn’t reduce the stress. Each of the characters learns more about themselves and their paths as demigods, with Jason realizing that his heart isn’t with the Roman camp. Piper recognizes she has been underestimating herself. Frank comes into his power as a shifter and his improving battle skills. Leo falling in love with Calypso and leaving wasn’t surprising, but his swearing on the River of Styx was shocking. It will be interesting to see how that will come back to bite him. My all-time favorite, Nico, is the same as always being dark and broody. In this book, we find out Nico’s sexuality, and it was not surprising that his crush was on Percy. Nico didn’t change as the others did, instead, he is forced to confront his love of Percy and is still pissed off. I love him for it. Jason tells Nico that his sexuality will not change how others view him. But, it’s not apparent if Nico believes Jason since Jason is the ‘golden boy.’ I loved every character in this book but I respect this book even more for deepening Nico’s character and letting us inside his head, something that I’ve wanted since his first introduction.

What a ride! 

The character development and relationships between the crew were incredible! A super enjoyable read, and might actually be one of my favorite books so far in both the PJO/HoO series! 

Now for a short break from the universe before I probably get my heart broken in the fifth book. 

-gonna leave myself a reminder to re-read this for the Calypso arc.

this was a 5 star read when i was 12 and it’s still a 5 star read now!!!! best book in the series truly. this is my favorite cover in the series. THE TEARS I SHED READING THE LAST LIKE 50 PAGES AND THE LAST LINE OF THE BOOK!!!!

           Throughout the House of Hades there were tense moments and great action scenes. Nico's revelation about his sexuality was really surprising because I really didn't expect Rick Riordan to bring in issues like this into the series. Percy's and Annabeth's experiences in Tartarus were fascinating and there were many moments where they came close to death but of course survived. Also Leo meeting Calypso was adorable ;) There wasn't a huge cliff-hanger at the end of the book compared to the previous book but nevertheless I can't wait to read the last book of the series !

In 2012 I first heard about the Percy Jackson series, a fictional series about the children of Greek Gods (aka demigods). I read the books and fell in love with the characters, the story, everything! Then, I found out there was a sequel series called The Heroes of Olympus, featuring old characters but also new characters. Including the most important: Jason, Piper, Leo, Hazel and Frank. These books feature more Greek (and also Roman) heroes, gods, monsters and much much more!

The House of Hades is the fourth book in the series. It starts off a couple of days (hours?) after Percy and Annabeth fell into Tartarus (which is like the worst part of Hell. It's the place where the monsters come from). The rest of the team doesn't know what to do after losing their 'leaders', but they decide to not let Percy and Annabeth's sacrifice be in vain. They travel from Italy to Greece - with several detours and monster attacks along the way - in order to close the Doors of Death. Meanwhile - in Tartarus - Percy and Annabeth are struggling to get to their side of the Doors, but they get help from some very unexpected companions.

Personally, I like the story of the Percy Jackson series better, but I like the writing style of these books more. The Heroes of Olympus books feel a lot more 'grown-up', or at least they feel more YA than the PJ books, which were definitely books for kids around the age of 12. I did enjoy these books though, because it was more of the Greek demigods which I love, and then with the Romans added made it even more awesome (okay technically, the Roman gods are the exact same as the Greek ones, except they have different names, and sometimes a god(dess) has one or two different 'powers' in Roman than they have in Greek).

My favourite chapters had to be the ones from Percy or Annabeth's POV, mainly because I wanted to know how their journey through Tartarus went. The descriptions of that place were incredibly awful though, and it made me a bit terrified. I probably wouldn't have been as brave as those two if I ended up in a place like that, also I probably would have died almost instantly. But Percy and Annabeth are of course 'professional' demigods, and they know how to fight and survive. Still, I was so afraid for them throughout the whole book, and I was so convinced something was going to go wrong.

The writing was, as usual, very good and I just couldn't stop reading. I guess I finished two/thirds of the story within this weekend, mainly because I hadn't read a thing during the previous week and I just wanted to finish a book. But the writing in THoH just made me want to read and read and read. I just love how Riordan is able to mix drama with humour, I have several quotes marked that just made me laugh out loud. I do believe that demigods have the worst luck EVER, because every time they seem to be safe, they get attacked by something else again. Maybe that's the problem of having such a big book, stuff needs to keep happening in order for it to be exciting. That was the only thing I didn't really like about this book - that a lot of the fights just seemed to be added to fill up the book and delay the demigods even further, ha ha ha!

In the end, I really really liked The House of Hades and I both can't and can wait to get my hands on the last book in this series, The Blood of Olympus. Then, after that I will pick up Riordan's new demigod series; Magnus Chase and the Gods of Asgard - YES, a book about Norse Goods, woohooooooo!
