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.
Words cannot explain how incredibly disappointed I am with this book. Everything about this book was not what I expected. Parts of it were written poorly, unnecessary parts were added and necessary perspectives were taken out. Certain parts felt rushed and the only thing I thought that kept this book together at all was the bits of humor scattered throughout. Other than that, the ending was nothing like the Last Olympian and for someone whose been with the series and the characters for the past six years, this was not how I wanted the series to end.
