The Dark Prophecy by Rick Riordan

Get me a legion

And about six tons of rocks

Need to kill a snake

I DO NOT LIKE SERPENTS.

Ever since my famous battle with Python, I’ve had a phobia of scaly reptilian creatures. (Especially if you include my stepmother, Hera. BOOM!) I could barely tolerate the snakes on Hermes’s caduceus, George and Martha. They were friendly enough, but they constantly pestered me to write a song for them about the joy of eating rats—a joy I did not share.

I told myself the creature in the Central Canal wasn’t an aquatic serpent. The water was much too cold. The canal didn’t offer enough tasty fish to eat.

On the other hand, I knew Commodus. He loved to collect exotic monsters. I could think of one particular river serpent he would love—one that might easily sustain itself by eating tasty pedal-boaters….

Bad Apollo!I told myself. Stay focused on your mission!

We chugged along for another fifty feet or so, long enough for me to wonder if the threat had been imaginary. Perhaps the monster had been nothing more than an abandoned pet alligator. Did they have those in the Midwest? Very polite ones, perhaps?

Leo nudged me. “Look over there.”

On the far embankment wall, peeking above the waterline, was the brick archway of an old sewer main, the entrance blocked by golden bars.

“How many sewers have you seen with gold grates on them?” Leo asked. “Betcha that one leads right to the emperor’s palace.”

I frowned. “That was much too easy.”

“Hey.” Meg poked me in the back of the neck. “Remember what Percy told us? Never say stuff like We made it or That was easy. You’ll jinx us!”

“My entire existence is a jinx.”

“Pedal faster.”

Since that was a direct order from Meg, I had no choice. My legs already felt like they were turning into sacks of hot coals, but I picked up the pace. Leo steered our teal plastic pirate ship toward the sewer entrance.

We were ten feet away when we triggered the First Law of Percy Jackson. Our jinx rose from the water in the form of a glistening arc of serpentine flesh.

I may have screamed. Leo shouted a completely unhelpful warning: “Look out!”

The boat tilted sideways. More arcs of serpent flesh breached around us—undulating hills of green and brown ridged with serrated dorsal fins. Meg’s twin blades flashed into existence. She tried to stand, but the pedal boat capsized, plunging us into a cold green explosion of bubbles and thrashing limbs.

My only consolation: the canal was not deep. My feet found the bottom and I was able to stand, gasping and shivering, the water up to my shoulders. Nearby, a three-foot-diameter coil of serpent flesh encircled our pedal boat and squeezed. The hull imploded, shattering teal plastic with a sound like firecrackers. One shard stung my face, narrowly missing my left eye.

Leo popped to the surface, his chin barely at water level. He waded toward the sewer grate, climbing over a hill of serpent flesh that got in his way. Meg, bless her heroic heart, slashed away at the monster’s coils, but her blades just skidded off its slimy hide.

Then the creature’s head rose from the canal, and I lost all hope that we would be home in time for tofu enchilada night.

The monster’s triangular forehead was wide enough to provide parking for a compact car. Its eyes glowed as orange as Agamethus’s ghost. When it opened its vast red maw, I remembered another reason I hate serpents. Their breath smells worse than Hephaestus’s work shirts.

The creature snapped at Meg. Despite being neck-deep in water, she somehow sidestepped and thrust her left-handed blade straight into the serpent’s eye.

The monster threw its head back and hissed. The canal boiled with snake flesh. I was swept off my feet and submerged once more.

When I came to the surface, Meg McCaffrey stood at my side, her chest heaving as she gasped for air, her glasses crooked and filmed with canal water. The serpent’s head flailed from side to side as if trying to shake the blindness out of its wounded eye. Its jaw smacked against the nearest condominium building, shattering windows and webbing the brick wall with cracks. A banner along the roofline said LEASING SOON! I hoped that meant the building was empty.

Leo made it to the grate. He traced his fingers along the golden bars, perhaps looking for buttons or switches or traps. Meg and I were now thirty feet away from him, which seemed a great distance over the vast serpentine terrain.

“Hurry!” I called to him.

“Gee, thanks!” he yelled back. “I didn’t think of that.”

The canal churned as the serpent drew in its coils. Its head rose two stories above us. Its right eye had gone dark, but its glowing left iris and its hideous maw reminded me of those pumpkin things mortals make for Halloween—jack-o’-lanterns? A silly tradition. I always preferred running around in goatskins at Februalia. Much more dignified.

Meg stabbed at the creature’s underbelly. Her golden blade only sparked against it.

“What is this thing?” she demanded.

“The Carthaginian Serpent,” I said. “One of the most fearsome beasts ever to face Roman troops. In Africa, it almost drowned an entire legion under Marcus Atilius Regulus—”

“Don’t care.” Meg and the serpent eyed each other warily—as if a giant monster and a twelve-year-old girl were well-matched opponents. “How do I kill it?”

My mind raced. I didn’t do well in panic situations, which meant most of the situations I had been in recently. “I—I think the legion finally crushed it with thousands of rocks.”

“I don’t have a legion,” Meg said. “Or thousands of rocks.”

The serpent hissed, spraying venom across the canal. I unslung my bow, but I ran into that pesky maintenance issue again. A wet bowstring and arrows were problematic, especially if I planned to hit a target as small as the serpent’s other eye. Then there were the physics of firing a bow while shoulder-deep in water.

“Leo?” I called.

“Almost!” He banged a wrench against the grate. “Keep it distracted!”

I gulped. “Meg, perhaps if you could stab its other eye, or its mouth.”

“While you do what, hide?”

I really hated how this young girl could get inside my brain. “Of course not! I’ll just be, um—”

The serpent struck. Meg and I dove in opposite directions. The creature’s head caused a tsunami between us, somersaulting me through the water. I swallowed a few gallons of the canal and came up spluttering, then gagged in horror when I saw Meg encircled in the snake’s tail. The serpent lifted her out of the water, bringing her level with its remaining eye. Meg slashed wildly, but the monster kept her out of striking distance. It regarded her as if thinking, What is this stoplight-colored thing?

Then it began to squeeze.

Leo yelled, “I got it!”

Clang.The grate’s golden bars swung inward.

Leo turned, grinning in pride, then saw Meg’s predicament.

“Nuh-uh!” He raised his hand above the water and tried to summon fire. All he managed was a puff of steam. He threw a wrench that bounced harmlessly off the snake’s side.

Meg yelped. The snake’s tail constricted around her waist, turning her face tomato red. She hammered her swords uselessly against the monster’s hide.

I stood paralyzed, unable to help, unable to think.

I knew the strength of such a serpent. I remembered being wrapped in Python’s coils, my divine ribs cracking, my godly ichor being squeezed into my head and threatening to spurt out my ears.

“Meg!” I shouted. “Hold on!”

She glared down at me, her eyes bulging, her tongue swollen, as if thinking, Like I have a choice?

The serpent ignored me, no doubt too interested in watching Meg implode like the pedal boat. Behind the snake’s head rose the damaged brick wall of a condominium. The sewer entrance stood just to the right of that.

I remembered the tale of the Roman legion that had once fought this thing by showering it with stones. If only that brick wall were part of the Waystation, and I could command it….

The idea seized me like a coil of the monster.

“Leo!” I yelled. “Get in the tunnel!”

“But—”

“Do it!”

Something began to swell inside my chest. I hoped it was power and not my breakfast.

I filled my lungs and bellowed in the baritone voice I usually reserved for Italian operas: “BEGONE, SNAKE! I AM APOLLO!”

The frequency was perfect.

The wall of the warehouse trembled and cracked. A three-story-tall curtain of bricks peeled away and collapsed onto the serpent’s back, pushing its head underwater. Its coiled tail loosened. Meg dropped into the canal.

Ignoring the rain of bricks, I waded forward (quite bravely, I thought) and pulled Meg to the surface.

“Guys, hurry!” Leo yelled. “The grate’s closing again!”

I dragged Meg toward the sewer (because that’s what friends are for) as Leo did his best to wedge the grate open with a tire iron.

Thank goodness for scrawny mortal bodies! We squeezed through just as the bars locked into place behind us.

Outside, the serpent surged upward from its baptism of bricks. It hissed and banged its half-blind head against the grate, but we did not linger to chat. We forged on, into the darkness of the emperor’s waterworks.
