Though the Greek and Roman crew members of the Argo II have made progress in their many quests, they still seem no closer to defeating the earth mother, Gaea. Her giants have risen - all of them - and they're stronger than ever. They must be stopped before the Feast of Spes, when Gaea plans to have two demigods sacrificed in Athens.

    I have read most of the books that Rick Riordan has wrote within the past few years and they were cool. He puts little funny things in it too.

          This book is another book about Percy Jackson I did not like it very much because, in my opinion, it was very boring and didn't have enough action.

            The seven have to save Olympus before it collapses. Some of them have fears of their own like what if something goes wrong or what if I die because of a choice I made? That however makes them want to save Olympus and the entire world even more than before. And they know just how to do that. I think that their determination also has an effect in our real lives too. I think that determination can lead you to do great things.

              I absolutely loved this book! It was the best book I have ever read so far. I love how the huge battle turns out, even though a hero dies (sniff) (maybe)

                Has action, humor and courage. Lovely book! It's a good way to end the season, but I'll miss the Heroes of Olympus series. The book has great role models too.

                  This is the conclusion to one of my favorite book series of all time. Everything has reached a climax as the books come to a close. It's packed full of all the exciting adventure of the previous books, I would definitely recommend the whole series!

                      I really love this book and this series, it is like my all-time favorite. there are so many relationships going on and so much action! It does not get boring at all and is very suspenseful.
