The stakes have never been higher. If Percy Jackson and Annabeth fail in their quest, there'll be hell on Earth. Literally. Wandering the deadly realm of Tartarus, every step leads them further into danger.

And, if by some miracle they do make it to the Doors of Death, there's a legion of bloodthirsty monsters waiting for them. Meanwhile, Hazel and the crew of the Argo II have a choice: to stop a war or save their friends.

Whichever road they take one thing is certain - in the Underworld, evil is inescapable.


從來沒有這麼危險過！ 如果波西‧傑克森和安娜貝斯這次的行動不幸失敗，地球就會陷入水深火熱！他們在稱作塔耳塔洛斯的冥界裡徘徊，每走一步就愈深陷險境之中。

而且，就算他們真的奇蹟般找到死亡之門 ，那兒也會一大群噬血的怪獸軍團等待著他們。在此同時，海柔和飛船阿爾戈二號上的同夥得做出選擇：是要阻止戰爭，還是拯救朋友為先？

不管他們的選擇為何，有件事絕對錯不了，那就是只要身處地獄，就逃不出萬惡的魔掌。
