The House of Hades (The Heroes of Olympus 4)

The idea made Annabeth giddy with homesickness. At every meal, the campers would burn a portion of their food to honor their godly parents. The smoke supposedly pleased the gods, but Annabeth had never thought about where the food went when it was burned. Maybe the offerings reappeared on the gods’ altars in Olympus…or even here, in the middle of Tartarus.

“Peanut M&M’s,” Annabeth said. “Connor Stoll always burned a pack for his dad at dinner. ”

She thought about sitting in the dining pavilion, watching the sunset over Long Island Sound. That was the first place she and Percy had truly kissed. Her eyes smarted.

Percy put his hand on her shoulder. “Hey, this is good. Actual food from home, right?”

She nodded. They finished eating in silence.

Bob chomped down the last of his M&M’s. “Should go now. They will be here in a few minutes. ”

“A few minutes?” Annabeth reached for her dagger, then remembered she didn’t have it.

“Yes…well, I think minutes…” Bob scratched his silvery hair. “Time is hard in Tartarus. Not the same. ”

Percy crept to the edge of the crater. He peered back the way they’d come. “I don’t see anything, but that doesn’t mean much. Bob, which giants are we talking about? Which Titans?”

Bob grunted. “Not sure of names. Six, maybe seven. I can sense them. ”

“Six or seven?” Annabeth wasn’t sure her barbecue would stay down. “And can they sense you?”

“Don’t know. ” Bob smiled. “Bob is different! But they can smell demigods, yes. You two smell very strong. Good strong. Like…hmm. Like buttery bread!”

“Buttery bread,” Annabeth said. “Well, that’s great. ”

Percy climbed back to the altar. “Is it possible to kill a giant in Tartarus? I mean, since we don’t have a god to help us?”

He looked at Annabeth as if she actually had an answer.

“Percy, I don’t know. Traveling in Tartarus, fighting monsters here…it’s never been done before. Maybe Bob could help us kill a giant? Maybe a Titan would count as a god? I just don’t know. ”

“Yeah,” Percy said. “Okay. ”

She could see the worry in his eyes. For years, he’d depended on her for answers. Now, when he needed her most, she couldn’t help. She hated being so clueless, but nothing she’d ever learned at camp had prepared her for Tartarus. There was only one thing she was sure of: they had to keep moving. They couldn’t be caught by six or seven hostile immortals.

She stood, still disoriented from her nightmares. Bob started cleaning up, collecting their trash in a little pile, using his squirt bottle to wipe off the altar.

“Where to now?” Annabeth asked.

Percy pointed at the stormy wall of darkness. “Bob says that way. Apparently the Doors of Death—”

“You told him?” Annabeth didn’t mean it to come out so harsh, but Percy winced.

“While you were asleep,” he admitted. “Annabeth, Bob can help. We need a guide. ”

“Bob helps!” Bob agreed. “Into the Dark Lands. The Doors of Death…hmm, walking straight to them would be bad. Too many monsters gathered there. Even Bob could not sweep that many. They would kill Percy and Annabeth in about two seconds. ” The Titan frowned. “I think seconds. Time is hard in Tartarus. ”

“Right,” Annabeth grumbled. “So is there another way?”

“Hiding,” said Bob. “The Death Mist could hide you. ”

“Oh…” Annabeth suddenly felt very small in the shadow of the Titan. “Uh, what is Death Mist?”

“It is dangerous,” Bob said. “But if the lady will give you Death Mist, it might hide you. If we can avoid Night. The lady is very close to Night. That is bad. ”

“The lady,” Percy repeated.

“Yes. ” Bob pointed ahead of them into the inky blackness. “We should go. ”

Percy glanced at Annabeth, obviously hoping for guidance, but she had none. She was thinking about her nightmare—Thalia’s tree splintered by lightning, Gaea rising on the hillside and unleashing her monsters on Camp Half-Blood.

“Okay, then,” Percy said. “I guess we’ll see a lady about some Death Mist. ”

“Wait,” Annabeth said.

Her mind was buzzing. She thought of her dream about Luke and Thalia. She recalled the stories Luke had told her about his father, Hermes—god of travelers, guide to the spirits of the dead, god of communication.

She stared at the black altar.

“Annabeth?” Percy sounded concerned.

She walked to the pile of trash and picked out a reasonably clean paper napkin.

She remembered her vision of Reyna, standing in the smoking crevice beneath the ruins of Thalia’s pine tree, speaking with the voice of Athena:

I must stand here. The Roman must bring me.

Hurry. The message must be sent.

“Bob,” she said, “offerings burned in the mortal world appear on this altar, right?”

Bob frowned uncomfortably, like he wasn’t ready for a pop quiz. “Yes?”

“So what happens if I burn something on the altar here?”

“Uh…”

“That’s all right,” Annabeth said. “You don’t know. Nobody knows, because it’s never been done. ”
