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. She needs their blood—the blood of Olympus—in order to wake.
The demigods are having more frequent visions of a terrible battle at Camp Half-Blood. The Roman legion from Camp Jupiter, led by Octavian, is almost within striking distance. Though it is tempting to take the Athena Parthenos to Athens to use as a secret weapon, the friends know that the huge statue belongs back on Long Island, where it "might" be able to stop a war between the two camps.
The Athena Parthenos will go west; the Argo II will go east. The gods, still suffering from multiple personality disorder, are useless. How can a handful of young demigods hope to persevere against Gaea's army of powerful giants? As dangerous as it is to head to Athens, they have no other option. They have sacrificed too much already. And if Gaea wakes, it is game over. Published October 2014. Fifth book in Heroes of Olympus series. Check it out on Goodreads! 5 stars. Rick Riordan is a very talented author. I've enjoyed the previous books in both Percy Jackson series and the Kane Chronicles too. And this book, the conclusion to the Heroes of Olympus series, was no different. What I liked: Everything pretty much. The adventure in this book is one of my favorites, 100%. You're going between Leo's ship with the heroes on it like Jason, Piper, Annabeth, Percy, Hazel, and Frank and Reina who has the Mark of Athena (giant athena statue) and is trying to get it to Camp Half-Blood in time to stop a war between the two camps. She has Nico and Coach Hedge with her. So you've got two groups, going against odds that have been set against them from the start. I feel like the writing was beautifully done. With each page I got more and more into the story and he built up to the ending really well. There was a desperation of the heroes trying to get to where they needed to be and to be ready and you really feel it as the reader. I know I started reading at a much faster pace! ;) I also really liked that we got to know Reina better as she's one of the new characters. There are also a lot of twists with her character, things reappearing from her past. I thought the plot was nicely tied together and it helped to tie up there series as well. I thought the pieces fit together very nicely. What I didn't like: The last battle seemed to be over too quickly. Yes, the ways they defeated Gaea made sense I suppose, but it still felt like it was over too quickly for everything that had been building up to it. And then with Leo (dodging spoilers here) his end part was a bit weird too. AS far as I can remember the ending was the only thing that I wasn't happy with though. Overall, it was a nice ending to the Percy Jackson stories. I'm sure it's by no means the end to their adventures, but maybe just an end to the ones we'll hear of. It was an exciting book and one that I read through quite quickly. I thought the plot was good, there were some nice twists and it certainly got very tense towards the end of the book. I didn't like the final battle with Gaea as much, but the rest of the book was wonderful. The characters get chances to shine and it's lovely to see how far they've progressed and matured. And I was very happy with it as the final book.
