Moon girl (percy jackson x oc)

Part 25

Adelia's POV:

We ran through the exhibits and ducked behind a tour group. I looked for our friends, but I couldn't see them anywhere. Where was the dam snack bar?

"Stop!" The metal-detector guy yelled.

There was no place to go but into an elevator with the tour group. I ducked inside pulling Percy with me just as the door closed.

"We'll be going down seven hundred feet," our tour guide said cheerfully. She was a park ranger, with long black hair pulled back in a ponytail and tinted glasses. I guess she hadn't noticed that I was being chased. "Don't worry, ladies and gentlemen, the elevator hardly ever breaks."

"Does this go to the snack bar?" I asked her.

A few people behind me chuckled. The tour guide looked at me. Something about her gaze made my skin tingle.

"To the turbines, young man," the lady said. "Weren't you listening to my fascinating presentation upstairs?"

"Oh, uh, sure. Is there another way out of the dam?" Percy asked

"It's a dead end," a tourist behind me said. "For heaven's sake. The only way out is the other elevator."

The doors opened.

"Go right ahead, folks," the tour guide told us. "Another ranger is waiting for you at the end of the corridor."

We didn't have much choice but to go out with the group.

"And you two," the tour guide called. I looked back. She'd taken off her glasses. Her eyes were startlingly gray, like storm clouds. "There is always a way out for those clever enough to find it."

The doors closed with the tour guide still inside, leaving us alone.

Before I could think too much about the woman in the elevator, a ding came from around the corner. The second elevator was opening, and I heard an unmistakable sound—the clattering of skeleton teeth.

I ran after the tour group, through a tunnel carved out of solid rock. Percy was right on my heels. Thank god for the Nymph races at camp. It seemed to run forever. The walls were moist, and the air hummed with electricity and the roar of water. I came out on a U-shaped balcony that overlooked this huge warehouse area. Fifty feet below, enormous turbines were running. It was a big room, but I didn't see any other exit, unless we wanted to jump into the turbines and get churned up to make electricity.

I didn't. I dunno about Percy he does dumb stuff all the time. It's quite infuriating but almost, almost endearing.

Another tour guide was talking over the microphone, telling the tourists about water supplies in Nevada. I prayed that Thalia, Zoe, and Grover were okay. They might already be captured, or eating at the dam snack bar, completely unaware that we were being surrounded. And stupid me: I had trapped us in a hole hundreds of feet below the surface.

I worked my way around the crowd, trying not to be too obvious about it. There was a hallway at the other side of the balcony—maybe some place I could hide. I kept my hand on Moonbreaker, ready to strike. Percy kept his hand on Riptide as well.

By the time we got to the opposite side of the balcony, my nerves were shot. We backed into the little hallway and watched the tunnel we'd come from.

Then right behind me I heard a sharp Chhh! like the voice of a skeleton.

Without thinking, I uncapped Moonbreaker and spun, slashing with my sword.

The girl I'd just tried to slice in half yelped and dropped her Kleenex.

"Oh my god.'" she shouted. "Do you always kill people when they blow their nose?"

The first thing that went through my head was that the sword hadn't hurt her. It had passed clean through her body, harmlessly. 

"You're mortal!" Percy said.

"Well no shit Sherlock!" I told him. Face slap 10,100. It's been going up a lot

She looked at me in disbelief. "What's that supposed to mean? Of course I'm mortal! How did you get that sword past security?"

"I didn't—Wait, you can see it's a sword?" Percy said. 

I turned to him, "For fucks sake Percy, tell her it isn't a sword she's mortal!"

The girl rolled her eyes, which were green like Percy's but not. Hers were an emerald green Percy's were like clashing waves and sea and...
