Hephaestus grumbled as he opened the book and raised an eyebrow at the title of the chapter. Reading the chapter title aloud for everyone to hear, they all turned to look at Percy.

"Yeah, It was pretty bad." Percy said as he grimaced.

Hephaestus realizing that Percy would say nothing more began to read.

(I'd love to tell you I had some deep revelation on my way down, that I came to terms with my own mortality, laughed in the face of death, et cetera. The truth? My only thought was: Aaaaggghhhhh! )

Everyone started sniggering.

(The river raced towards me at the speed of a truck. Wind ripped the breath from my lungs. Steeples and skyscrapers and bridges tumbled in and out of my vision. And then: Flaaa-boooom! A whiteout of bubbles. I sank through the murk, sure that I was about to end up embedded in fifty metres of mud and lost forever. But my impact with the water hadn't hurt. I was falling slowly now, bubbles trickling up through my fingers. I settled on the river bottom soundlessly. A catfish the size of my stepfather lurched away into the gloom. Clouds of silt and disgusting garbage – beer bottles, old shoes, plastic bags – swirled up all around me. )

Hermes, Demeter, Grover, and Dionysus all grimaced at the state of the environment.

"Disgusting." Poseidon said grimacing.

(At that point, I realized a few things: first, I had not been flattened into a pancake. I had not been barbecued. I couldn't even feel the Chimera poison boiling in my veins any more. I was alive, which was good. )

"No, crap, Prissy." Clarisse said rolling her eyes.

(Second realization: I wasn't wet. I mean, I could feel the coolness of the water. I could see where the fire on my clothes had been quenched. But when I touched my own shirt, it felt perfectly dry. I looked at the garbage floating by and snatched an old cigarette lighter. No way, I thought. I flicked the lighter. It sparked. A tiny flame appeared, right there at the bottom of the Mississippi. )

"No way." Leo said excitedly.

"Could you do that with me underwater?" He asks Percy while lighting himself on fire.

Percy looked at him in shock before grinning.

"I don't know. Probably but the problem is with your breathing as you can't breathe underwater." Percy points out.

"Aww." Leo says as he pouts and his fire goes out.

(I grabbed a soggy hamburger wrapper out of the current and immediately the paper turned dry. I lit it with no problem. As soon as I let it go, the flames sputtered out. The wrapper turned back into a slimy rag. Weird. )

"You should have let it burn up. That way it's not clogging up the environment." Poseidon told his son.

Percy nodded, grimacing.

(But the strangest thought occurred to me only last: I was breathing. I was underwater, and I was breathing normally. )

"It took you long enough." Katie said shaking her head.

(I stood up, thigh-deep in mud. My legs felt shaky. My hands trembled. I should've been dead. The fact that I wasn't seemed like… well, a miracle. I imagined a woman's voice, a voice that sounded a bit like my mother: Percy, what do you say? Um… thanks. Underwater, I sounded like I did on recordings, like a much older kid. Thank you… Father. )

"It wasn't me, Percy, but your own powers." Poseidon said to his son, smiling.

"Yeah, I know now but back then I didn't." Percy said shrugging.

(No response. Just the dark drift of garbage downriver, the enormous catfish gliding by, the flash of sunset on the water's surface far above, turning everything the colour of butterscotch. )

Everyone grimaced at the disgustingness of the river.

(Why had Poseidon saved me? The more I thought about it, the more ashamed I felt. So I'd got lucky a few times before. Against a thing like the Chimera, I had never stood a chance. Those poor people in the Arch were probably toast. I couldn't protect them. I was no hero. Maybe I should just stay down here with the catfish, join the bottom feeders. )

Poseidon frowned at the thoughts of his son.

(Fump-fump-fump. A riverboat's paddlewheel churned above me, swirling the silt around. There, not two metres in front of me, was my sword, its gleaming bronze hilt sticking up in the mud. I heard that woman's voice again: Percy, take the sword. Your father believes in you. This time, I knew the voice wasn't in my head. I wasn't imagining it. Her words seemed to come from everywhere, rippling through the water like dolphin sonar. )

Poseidon leaned forward, wondering if he sent someone to Percy.

('Where are you?' I called aloud. Then, through the gloom, I saw her – a woman the colour of the water, a ghost in the current, floating just above the sword. She had long billowing hair, and her eyes, barely visible, were green like mine. A lump formed in my throat. I said, 'Mom?' )

Poseidon and Percy frowned at the similarities between the naiad and Sally.

(No, child, only a messenger, though your mother's fate is not as hopeless as you believe. Go to the beach in Santa Monica. 'What?' It is your father's will. Before you descend into the Underworld, you must go to Santa Monica. Please, Percy, I cannot stay long. The river here is too foul for my presence. 'But…' I was sure this woman was my mother, or a vision of her, anyway. 'Who – how did you –' )

Hera smiled at how much the boy needed his mother.

Hermes wondered if Sally was a distinct granddaughter or something similar to the Naiads.

(There was so much I wanted to ask, the words jammed up in my throat. I cannot stay, brave one, the woman said. She reached out, and I felt the current brush my face like a caress. You must go to Santa Monica! And, Percy, do not trust the gifts… Her voice faded. 'Gifts?' I asked. 'What gifts? Wait!' )

"Have they gotten any gifts, yet?" Demeter asked, frowning.

"The pen-sword that Percy was given, and the shoes the son of Hermes gave them at the start but she could have been talking about a gift later on." Athena theorized.

(She made one more attempt to speak, but the sound was gone. Her image melted away. If it was my mother, I had lost her again. I felt like drowning myself. The only problem: I was immune to drowning. )

Poseidon frowned at that thought his son had.

"I don't have those thoughts anymore. Well, I didn't until a weeks ago where I woke up with no memories." Percy said while glaring at Hera.

(Your father believes in you, she had said. She'd also called me brave… unless she was talking to the catfish. I waded towards Riptide and grabbed it by the hilt. The Chimera might still be up there with its snaky fat mother, waiting to finish me off. At the very least, the mortal police would be arriving, trying to figure out who had blown a hole in the Arch. If they found me, they'd have some questions. )

"Quite a bit of questions that you won't be able to answer." Rachel said smirking.

(I capped my sword, stuck the ballpoint pen in my pocket. 'Thank you, Father,' I said again to the dark water. Then I kicked up through the muck and swam for the surface. )

"Once again, not anything you need to thank me for." Poseidon told his son.

(I came ashore next to a floating McDonald's. )

Nico started fantasizing about McDonald's.

Will and Percy rolled their eyes at the son of Hades.

(A block away, every emergency vehicle in St Louis was surrounding the Arch. Police helicopters circled overhead. The crowd of onlookers reminded me of Times Square on New Year's Eve. A little girl said, 'Mama! That boy walked out of the river.' 'That's nice, dear,' her mother said, craning her neck to watch the ambulances. 'But he's dry!' 'That's nice, dear.' )

"Children are usually able to see through the Mist as they are young and have much imagination." Demeter explained to the demigods.

(A news lady was talking for the camera: 'Probably not a terrorist attack, we're told, but it's still very early in the investigation. The damage, as you can see, is very serious. We're trying to get to some of the survivors, to question them about eyewitness reports of someone falling from the Arch.' Survivors. I felt a surge of relief. Maybe the park ranger and that family made it out safely. I hoped Annabeth and Grover were okay. I tried to push through the crowd to see what was going on inside the police line. '… an adolescent boy,' another reporter was saying. 'Channel Five has learned that surveillance cameras show an adolescent boy going wild on the observation deck, somehow setting off this freak explosion. Hard to believe, John, but that's what we're hearing. Again, no confirmed fatalities…' I backed away, trying to keep my head down. I had to go a long way around the police perimeter. Uniformed officers and news reporters were everywhere.)

"I watched this on TV. I didn't really know what had happened because my father had changed the channel before I could fully figure out what had happened." Rachel said bouncing in her seat.

( I'd almost lost hope of ever finding Annabeth and Grover when a familiar voice bleated, 'Perrr-cy!' I turned and got tackled by Grover's bear hug – or goat hug. He said, 'We thought you'd gone to Hades the hard way!' )

"Actually, you would have come to me the easiest way." Hades pointed out.

(Annabeth stood behind him, trying to look angry, but even she seemed relieved to see me. 'We can't leave you alone for five minutes! What happened?' 'I sort of fell.' 'Percy! Two hundred )metres?' Behind us, a cop shouted, 'Gangway!' The crowd parted, and a couple of paramedics hustled out, rolling a woman on a stretcher. I recognized her immediately as the mother of the little boy who'd been on the observation deck. She was saying, 'And then this huge dog, this huge fire-breathing Chihuahua –' )

Several of the Gods winced.

"That's gonna need to be taken care of."Hermes said, grimacing. "They must have clear-sightedness."

('Okay, ma'am,' the paramedic said. 'Just calm down. Your family is fine. The medication is starting to kick in.' 'I'm not crazy! This boy jumped out of the hole and the monster disappeared.' Then she saw me. 'There he is! That's the boy!' I turned quickly and pulled Annabeth and Grover after me. We disappeared into the crowd. 'What's going on?' Annabeth demanded. 'Was she talking about the Chihuahua on the elevator?' I told them the whole story of the Chimera, Echidna, my high-dive act, the underwater lady's message. 'Whoa,' said Grover. 'We've got to get you to Santa Monica! You can't ignore a summons from your dad.' )

"Well, I mean I could." Percy said, grinning at his dad.

Poseidon narrowed his eyes at Percy but grinned back; knowing his son was messing with him.

(Before Annabeth could respond, we passed another reporter doing a news break, and I almost froze in my tracks when he said, 'Percy Jackson. That's right, Dan. Channel Twelve has learned that the boy who may have caused this explosion fits the description of a young man wanted by the authorities for a serious New Jersey bus accident three days ago. And the boy is believed to be travelling west. For our viewers at home, here is a photo of Percy Jackson.' )

Everyone winced, knowing that this was not a good thing for the quest.

"This quest has been taken to a new level." Jason muttered.

(We ducked around the news van and slipped into an alley. 'First things first,' I told Grover. 'We've got to get out of town!' Somehow, we made it back to the Amtrak station without getting spotted. We got on board the train just before it pulled out for Denver. The train trundled west as darkness fell, police lights still pulsing against the St Louis skyline behind us. )

"Pretty sure the Gods were helping us get out of the city." Annabeth said to the room. "Cause the trains should have been the first thing the mortals stopped."

"Probably me." Hermes said raising a hand.

"How about you all take a slightly late lunch." Athena told the demigods.

The other Gods nodded.

"I hope the kitchen has McDonald's." Nico said as he shadowed traveled to the Kitchen.

"He didn't have my permission to use his powers like that." Will said as he stomped out the room, about to give Nico a piece of his mind.

The other demigods left the room in a calmer state. The Gods shared a look at how weird their children were.
