I tore across the Mall, not daring to look behind me. I burst into the Air and Space
Museum and took off my invisibility cap once I was through the admissions area.
The main part of the museum was one huge room with rockets and airplanes hanging
from the ceiling. Three levels of balconies curled around, so you could look at the exhibits
from all different heights. The place wasn't crowded, just a few families and a couple of tour
groups of kids, probably doing one of those holiday school trips. I wanted to yell at them all
to leave, but I figured that would only get me arrested. I had to find Thalia and Grover and the
Hunters. Any minute, the skeleton dudes were going to invade the museum, and I didn't think
they would settle for an audio tour.
I ran into Thalia—literally. I was barreling up the ramp to the top-floor balcony and
slammed into her, knocking her into an Apollo space capsule.
Grover yelped in surprise.
Before I could regain my balance, Zoe and Bianca had arrows notched, aimed at my
chest. Their bows had just appeared out of nowhere.
When Zoe realized who I was, she didn't seem anxious to lower her bow. "You! How
dare you show thy face here?"
"Percy!" Grover said. "Thank goodness."
Zoe glared at him, and he blushed. "I mean, um, gosh. You're not supposed to be here!"
"Luke," I said, trying to catch my breath. "He's here."
The anger in Thalia's eyes immediately melted. She put her hand on her silver bracelet.
"Where?"
I told them about the Natural History Museum, Dr. Thorn, Luke, and the General.
"The General is here?" Zoe looked stunned. "That is impossible! You lie."
"Why would I lie? Look, there's no time. Skeleton warriors—"
"What?" Thalia demanded. "How many?"
"Twelve," I said. "And that's not all. That guy, the General, he said he was sending
something, a 'playmate,' to distract you over here. A monster."
Thalia and Grover exchanged looks.
"We were following Artemis's trail," Grover said. "I was pretty sure it led here. Some
powerful monster scent… She must've stopped here looking for the mystery monster. But we
haven't found anything yet."
"Zoe," Bianca said nervously, "if it is the General—"
"It cannot be!" Zoe snapped. "Percy must have seen an Iris-message or some other
illusion."
"Illusions don't crack marble floors," I told her.
Zoe took a deep breath, trying to calm herself. I didn't know why she was taking it so
personally, or how she knew this General guy, but I figured now wasn't the time to ask. "If
Percy is telling the truth about the skeleton warriors," she said, "we have no time to argue.
They are the worst, the most horrible… We must leave now."
"Good idea," I said.
"I was not including thee, boy," Zoe said. "You are not part of this quest."
"Hey, I'm trying to save your lives!"
"You shouldn't have come, Percy," Thalia said grimly. "But you're here now. Come on.
Let's get back to the van."
"That is not thy decision!" Zoe snapped.
Thalia scowled at her. "You're not the boss here, Zoe. I don't care how old you
are!You're still a conceited little brat!"
"You never had any wisdom when it came to boys," Zoe growled. "You never could
leave them behind!"
Thalia looked like she was about to hit Zoe. Then everyone froze, I heard a growl so
loud I thought one of the rocket engines was starting up.
Below us, a few adults screamed. A little kid's voice screeched with delight: "Kitty!"
Something enormous bounded up the ramp. It was the size of a pick-up truck, with
silver claws and golden glittering fur. I'd seen this monster once before. Two years ago, I'd
glimpsed it briefly from a train. Now, up close and personal, it looked even bigger.
"The Nemean Lion," Thalia said. "Don't move."
The lion roared so loud it parted my hair. Its fangs gleamed like stainless steel.
"Separate on my mark," Zoe said. "Try to keep it distracted."
"Until when?" Grover asked.
"Until I think of a way to kill it. Go!"
I uncapped Riptide and rolled to the left. Arrows whistled past me, and Grover played a
sharp tweet-tweet cadence on his reed pipes. I turned and saw Zoe and Bianca climbing the
Apollo capsule. They were firing arrows, one after another, all shattering harmlessly against
the lions metallic fur. The lion swiped the capsule and tipped it on its side, spilling the
Hunters off the back. Grover played a frantic, horrible tune, and the lion turned toward him,
but Thalia stepped into its path, holding up Aegis, and the lion recoiled. "ROOOAAAR!"
"Hi-yah!" Thalia said. "Back!"
The lion growled and clawed the air, but it retreated as if the shield were a blazing fire.
For a second, I thought Thalia had it under control. Then I saw the lion crouching, its
leg muscles tensing. I'd seen enough cat fights in the alleys around my apartment in New
York. I knew the lion was going to pounce.
"Hey!" I yelled. I don't know what I was thinking, but I charged the beast. I just wanted
to get it away from my friends. I slashed with Riptide, a good strike to the flank that should've
cut the monster into Meow Mix, but the blade just clanged against its fur in a burst of sparks.
The lion raked me with its claws, ripping off a chunk of my coat. I backed against the
railing. It sprang at me, one thousand pounds of monster, and I had no choice but to turn and
jump.
I landed on the wing of an old-fashioned silver airplane, which pitched and almost
spilled me to the floor, three stories below.
An arrow whizzed past my head. The lion jumped onto the aircraft, and the cords
holding the plane began to groan.
The lion swiped at me, and I dropped onto the next exhibit, a weird-looking spacecraft
with blades like a helicopter. I looked up and saw the lion roar—inside its maw, a pink tongue
and throat.
Its mouth, I thought. Its fur was completely invulnerable, but if I could strike it in the
mouth… The only problem was, the monster moved too quickly. Between its claws and
fangs, I couldn't get close without getting sliced to pieces.
"Zoe!" I shouted. "Target the mouth!"
The monster lunged. An arrow zipped past it, missing completely, and I dropped from
the spaceship onto the top of a floor exhibit, a huge model of the earth. I slid down Russia and
dropped off the equator.
The Nemean Lion growled and steadied itself on the spacecraft, but its weight was too
much. One of the cords snapped. As the display swung down like a pendulum, the lion leaped
off onto the model earth's North Pole.
"Grover!" I yelled. "Clear the area!"
Groups of kids were running around screaming. Grover tried to corral them away from
the monster just as the other cord on the spaceship snapped and the exhibit crashed to the
floor. Thalia dropped off the second-floor railing and landed across from me, on the other side
of the globe. The lion regarded us both, trying to decide which of us to kill first.
Zoe and Bianca were above us, bows ready, but they kept having to move around to get
a good angle.
"No clear shot!" Zoe yelled. "Get it to open its mouth more!"
The lion snarled from the top of the globe.
I looked around. Options. I needed…
The gift shop. I had a vague memory from my trip here as a little kid. Something I'd
made my mom buy me, and I'd regretted it. If they still sold that stuff…
"Thalia," I said, "keep it occupied."
She nodded grimly.
"Hi-yah!" She pointed her spear and a spidery arc of blue electricity shot out, zapping
the lion in the tail.
"ROOOOOOOAR!" The lion turned and pounced. Thalia rolled out of its way, holding
up Aegis to keep the monster at bay, and I ran for the gift shop.
"This is no time for souvenirs, boy!" Zoe yelled.
I dashed into the shop, knocking over rows of T-shirts, jumping over tables full of glowin-the-dark planets and space ooze. The sales lady didn't protest. She was too busy cowering
behind her cash register.
There! On the far wall—glittery silver packets. Whole racks of them. I scooped up
every kind I could find and ran out of the shop with an armful.
Zoe and Bianca were still showering arrows on the monster, but it was no good. The
lion seemed to know better than to open its mouth too much. It snapped at Thalia, slashing
with its claws. It even kept its eyes narrowed to tiny slits.
Thalia jabbed at the monster and backed up. The lion pressed her.
"Percy," she called, "whatever you're going to do—"
The lion roared and swatted her like a cat toy, sending her flying into the side of a Titan
rocket. Her head hit the metal and she slid to the floor.
"Hey!" I yelled at the lion. I was too far away to strike, so I took a risk: I hurled Riptide
like a throwing knife. It bounced off the lion's side, but that was enough to get the monster's
attention. It turned toward me and snarled.
There was only one way to get close enough. I charged, and as the lion leaped to
intercept me, I chunked a space food pouch into its maw—a chunk of cellophane-wrapped,
freeze-dried strawberry parfait.
The lion's eyes got wide and it gagged like a cat with a hairball.
I couldn't blame it. I remembered feeling the same way when I'd tried to eat space food
as a kid. The stuff was just plain nasty.
"Zoe, get ready!" I yelled.
Behind me, I could hear people screaming. Grover was playing another horrible song on
his pipes.
I scrambled away from the lion. It managed to choke down the space food packet and
looked at me with pure hate.
"Snack time!" I yelled.
It made the mistake of roaring at me, and I got an ice-cream sandwich in its throat.
Fortunately, I had always been a pretty good pitcher, even though baseball wasn't my game.
Before the lion could stop gagging, I shot in two more flavors of ice cream and a freeze-dried
spaghetti dinner.
The lion's eyes bugged. It opened its mouth wide and reared up on its back paws, trying
to get away from me.
"Now!" I yelled.
Immediately, arrows pierced the lion's maw—two, four, six. The lion thrashed wildly,
turned, and fell backward. And then it was still.
Alarms wailed throughout the museum. People were flocking to the exits. Security
guards were running around in a panic with no idea what was going on.
Grover knelt at Thalia's side and helped her up. She seemed okay, just a little dazed.
Zoe and Bianca dropped from the balcony and landed next to me.
Zoe eyed me cautiously. "That was… an interesting strategy."
"Hey, it worked."
She didn't argue.
The lion seemed to be melting, the way dead monsters do sometimes, until there was
nothing left but its glittering fur coat, and even that seemed to be shrinking to the size of a
normal lion's pelt.
"Take it," Zoe told me.
I stared at her. "What, the lion's fur? Isn't that, like, an animal rights violation or
something?"
"It is a spoil of war," she told me. "It is rightly thine."
"You killed it," I said.
She shook her head, almost smiling. "I think thy ice-cream sandwich did that. Fair is
fair, Percy Jackson. Take the fur."
I lifted it up; it was surprisingly light. The fur was smooth and soft. It didn't feel at all
like something that could stop a blade. As I watched, the pelt shifted and changed into a
coat—a full-length golden-brown duster.
"Not exactly my style," I murmured.
"We have to get out of here," Grover said. "The security guards won't stay confused for
long."
I noticed for the first time how strange it was that the guards hadn't rushed forward to
arrest us. They were scrambling in all directions except ours, like they were madly searching
for something. A few were running into the walls or each other.
"You did that?" I asked Grover.
He nodded, looking a little embarrassed. "A minor confusion song. I played some Barry
Manilow. It works every time. But it'll only last a few seconds."
"The security guards are not our biggest worry," Zoe said. "Look."
Through the glass walls of the museum, I could see a group of men walking across the
lawn. Gray men in gray camouflage outfits. They were too far away for us to see their eyes,
but I could feel their gaze aimed straight at me.
"Go," I said. "They'll be hunting me. I'll distract them."
"No," Zoe said. "We go together."
I stared at her. "But, you said—"
"You are part of this quest now," Zoe said grudgingly. "I do not like it, but there is no
changing fate. You are the fifth quest member. And we are not leaving anyone behind."
