The Son of Neptune (The Heroes of Olympus #2)(45)



Nico paused to let that sink in. “And if Alcyoneus has been reborn in Alaska—”

“Then he can’t be defeated there,” Hazel finished. “Ever. By any means. Which is why our nineteen-eighties expedition was doomed to fail.”

Another round of arguing and shouting broke out.

“The quest is impossible!” shouted a senator.

“We’re doomed!” cried a ghost.

“More Kool-Aid!” yelled Dakota.

“Silence!” Reyna called. “Senators, we must act like Romans. Mars has given us this quest, and we have to believe it is possible. These three demigods must travel to Alaska. They must free Thanatos and return before the Feast of Fortuna. If they can retrieve the lost eagle in the process, so much the better. All we can do is advise them and make sure they have a plan.”

Reyna looked at Percy without much hope. “You do have a plan?”

Percy wanted to step forward bravely and say, No, I don’t!

That was the truth, but looking around at all the nervous faces, Percy knew he couldn’t say it.

“First, I need to understand something.” He turned toward Nico. “I thought Pluto was the god of the dead. Now I hear about this other guy, Thanatos, and the Doors of Death from that prophecy—the Prophecy of Seven. What does all that mean?”

Nico took a deep breath. “Okay. Pluto is the god of the Underworld, but the actual god of death, the one who’s responsible for making sure souls go to the afterlife and stay there—that’s Pluto’s lieutenant, Thanatos. He’s like…well, imagine Life and Death are two different countries. Everybody would like to be in Life, right? So there’s a guarded border to keep people from crossing back over without permission. But it’s a big border, with lots of holes in the fence. Pluto tries to seal up the breaches, but new ones keep popping up all the time. That’s why he depends on Thanatos, who’s like the border patrol, the police.”

“Thanatos catches souls,” Percy said, “and deports them back to the Underworld.”

“Exactly,” Nico said. “But now Thanatos has been captured, chained up.”

Frank raised his hand. “Uh…how do you chain Death?”

“It’s been done before,” Nico said. “In the old days, a guy named Sisyphus tricked Death and tied him up. Another time, Hercules wrestled him to the ground.”

“And now a giant has captured him,” Percy said. “So if we could free Thanatos, then the dead would stay dead?” He glanced at Gwen. “Um…no offense.”

“It’s more complicated than that,” Nico said.

Octavian rolled his eyes. “Why does that not surprise me?”

“You mean the Doors of Death,” Reyna said, ignoring Octavian. “They are mentioned in the Prophecy of Seven, which sent the first expedition to Alaska—”

Cato the ghost snorted. “We all know how that turned out! We Lares remember!”

The other ghosts grumbled in agreement.

Nico put his finger to his lips. Suddenly all the Lares went silent. Some looked alarmed, like their mouths had been glued together. Percy wished he had that power over certain living people…like Octavian, for instance.

“Thanatos is only part of the solution,” Nico explained. “The Doors of Death…well, that’s a concept even I don’t completely understand. There are many ways into the Underworld—the River Styx, the Door of Orpheus—plussmaller escape routes that open up from time to time. With Thanatos imprisoned, all those exits will be easier to use. Sometimes it might work to our advantage and let a friendly soul come back—like Gwen here. More often, it will benefit evil souls and monsters, the sneaky ones who are looking to escape. Now, the Doors of Death—those are the personal doors of Thanatos, his fast lane between Life and Death. Only Thanatos is supposed to know where they are, and the location shifts over the ages. If I understand correctly, the Doors of Death have been forced open. Gaea’s minions have seized control of them—”

“Which means Gaea controls who can come back from the dead,” Percy guessed.

Nico nodded. “She can pick and choose who to let out—the worst monsters, the most evil souls. If we rescue Thanatos, that means at least he can catch souls again and send them below. Monsters will die when we kill them, like they used to, and we’ll get a little breathing room. But unless we’re able to retake the Doors of Death, our enemies won’t stay down for long. They’ll have an easy way back to the world of the living.”

“So we can catch them and deport them,” Percy summed up, “but they’ll just keep coming back across.”

“In a depressing nutshell, yes,” Nico said.

Frank scratched his head. “But Thanatos knows where the doors are, right? If we free him, he can retake them.”

“I don’t think so,” Nico said. “Not alone. He’s no match for Gaea. That would take a massive quest…an army of the best demigods.”

“Foes bear arms to the Doors of Death,” Reyna said. “That’s the Prophecy of Seven…” She looked at Percy, and for just a moment he could see how scared she was. She did a good job of hiding it, but Percy wondered if she’d had nightmares about Gaea too—if she’d seen visions of what would happen when the camp was invaded by monsters that couldn’t be killed. “If this begins the ancient prophecy, we don’t have resources to send an army to these Doors of Death and protect the camp. I can’t imagine even sparing seven demigods—”
