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 from 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.

        This is got to be the most dramatic part of the series that is pretty emotional. I won't say more. You gotta read it. It's really good.😍I love Greek mythology which has lead me to reading all of Rick Riordan's books and new ones coming up as well! It's so awsome how it has lead to the beginning of a new quest that literally completes the whole Heroes Of Olympus series! 😍🤓

          I want to read this book because Percy Jackson is amazing. The way Rick Riordan tells the stories is unbelievable. I have always loved the stories about adventures and mysteries. I have watched the movies of Percy Jackson and they were amazing. I loved them. That is why I want to read this book.

              This is the most amazing series I have read next to Harry Potter and the Percy Jackson series. I mostly enjoyed the Lost Hero but this was also a really good one, the part I hated was when Annabeth and Percy fall into Tartarus. But the crew goes on.

                I adored this book. Rick Riordan has wrote another great masterpiece. I waited for quite a while for the sequel after the cliffhanger of The Mark of the Athena. I was not disappointed at all. I would definitely recommend this story.

                  The House of Hades, another book in the Heroes of Olympus series, expresses yet another detailed and action packed story that mixes all the romance, heroism, and magic to make a perfect tale.

                    This is the 4th in the Percy Jackson series. After the cliffhanger in the last book i was ready to read this. During this book Percy and Annabeth made making their way through tartorus (sorry if that's spelled wrong) but its really hard because there's a bunch of monsters and titans. There's one nice titan his name is Bob. I like bobs cat small Bob☺☺☺ while Percy and annabeths trying to survive there friends are going rough a lot to go to the doors of death. During this book they are trying to prepare for a war. I tried not to spoil to much so if I spoiled the book I'm sorry. The one thing I didn't like was the CLIFFHANGER it made me mad but now I'm excited for the next book! Thanks for reading! 5/5🌟

                      This is my favorite book in the Heros of Olympus and Percy Jackson series. While Percy and Annabeth and making their way across the horrid landscape of Tartarus with the help of friends who should be foes, the other members of the Argo 2 face their own sets of challenges, and Nico, Reyna, and Coach Hedge set out to prevent another civil war. The House of Hades, along with the rest of the Heros of Olympus series is entertaining and easy to read!
