Bianca's POV

"Thermos!" Percy screamed as we hurtled toward the water.

"What?" Annabeth and I cried.

We were holding onto the boat straps for dear life. I felt the arrows and javelins whistling past us through the wind. I ducked, still clutching onto the straps.

"Hang on!" I heard Percy shout.

"We are!" Annabeth and I yelled in unison.

"Tighter!"

As I closed my eyes, I felt a strong gust of wind. I felt the boat bump the water. We were skipping like stones on the water and then, we were zooming across the water. I opened my eyes, feeling the water splash against me.

Is this what a Thermos does?

I smiled.

I like this.

There was a wail of outrage from the ship behind us. I turned around, seeing the Princess Andromeda fading to the size of a white toy boat in the distance. Soon, it was gone.

"We should send an Iris message to Chiron," Percy began.

Annabeth nodded.

Iris message?

The wind from the thermos stirred up a spray of water that created a rainbow in the sunlight. I watched Annabeth pull out a gold drachma and throw it into the water mist. She began to pray for this rainbow goddess to show us Chiron, and soon, his face appeared.

My face brightened.

However, I noticed that there was some kind of weird strobe light flashing in the background and rock music blaring. During this, we had a long conversation with him, explaining about how we snuck away from camp, Luke and the Princess Andromeda, and this coffin for this monster dude's remain. However, I wasn't sure if he could hear that between the noise on his end and the wind and waves on ours.

"Percy," Chiron called."You have to watch out for-" His voice was drowned out by the loud shouting behind him.

"What?" Percy yelled over the noise.

"Curse my relatives!" Chiron ducked as a plate flew over his head and shattered somewhere out of sight."Annabeth, you shouldn't have let Percy leave camp! But if you do get the Fleece-"

"Yeah, baby!" Somebody behind Chiron yelled."Woo-hoooooo!"

My eyes widened, hearing the music turn up louder.

"-Miami," Chiron continued."I'll try to keep watch-"

Soon, Chiron was gone.

"That was interesting," I spoke up.

During our boat ride, we spent forty-five minutes staring off into the view and then talking.

"You...what Luke said..." Annabeth began, staring at me.

I shrugged."Well, I don't know whatever prophecy he was talking about, that's for sure."

"You shot out ice at that man," Percy brought up.

"I'm the daughter of Khione, goddess of snow," I introduced myself.

"But...she's a minor goddess. Why would he say you are a part of this big prophecy?"

I smiled at Annabeth's cleverness."You're getting somewhere, Annabeth." I sighed."He is correct that I am hiding a secret from you guys but..."

"But?"

"Chiron told me not to tell anyone, so...I don't know..."

"We'll keep it a secret!" Tyson promised.

I gave a smiled.

"Is it something big?" Percy wondered.

I hesitated, then nodded."There is a whole another world out there than here," I began.

The ones I love from Hogwarts and the Burrow appeared in my mind.

I smiled, staring at the new people I befriended."I'm...I'm a witch," I confessed.

"Hecate's children?" Percy asked.

"Hm...something like that? I'm not really her daughter though..."

"You are a pretty witch! Not the ugly kind," Tyson said.

I smiled."Thanks, Tyson."

"So...you are the daughter of Khione and a somewhat descendant of Hecate?" Annabeth questioned.

"Hm...if you put it that way, yes."

I pulled out my wand from my duffel bag.

"A wand! You have a broom too?" Tyson wondered.

I chuckled."It's...back at home."

"How about spells? Like Abracadabra!"

I shook my head."I can't do spells here."

"So, he's saying that you're the most powerful one out of all?"

I shrugged."Aren't there people like me in Camp Half-Blood too?"

I noticed Percy and Annabeth look at each other and then back at me.

"Bianca, you would be called a god or goddess if the immortal parents mated together."

I frowned.

Who am I if there aren't people like me?

My eyes shifted off into the distance.

Why aren't there people like me here? This doesn't make sense. So, my mom mated with either a Muggle-born, Half-blood, or Pure-blood, and then I received both genes?

I sighed.

This is so confusing. There aren't people like me at Hogwarts... And there aren't people like me at Camp Half-Blood...Great...

"Bianca? You okay?" I heard Annabeth asked.

I shrugged."It's very disappointing to not know about my own background."

She sighed."You'll get there, Bianca. We all eventually get to know about ourselves."

Soon, we spotted land. The beach was lined with hotels. The water was crowded with fishing boats and tankers.

"That's Virginia Beach!" Annabeth pointed out as we approached the shoreline."Oh my gods, how did the Princess Andromeda travel so far overnight? That's like-"

"Five hundred and thirty nautical miles," Percy finished for her.

I stared at him."How did you know that?"

"I-I'm not sure."

"Wait..." Annabeth thought for a moment."Percy, what's our position?"

"36 degrees, 44 minutes north, 76 degrees, 2 minutes west," Percy instantly replied.

My jaw dropped.

Woah...

He shook my head."Whoa. How did I know that?"

"Because of your dad," Annabeth guessed. "When you're at sea, you have perfect bearings.

"That is so cool..." I gasped.

"Other boat is coming," Tyson mentioned.

We turned around.. There was a coast guard vessel definitely on our tail now. Its lights were flashing, and it was also gaining speed.

"We can't let them catch us. They'll ask too many questions," Percy told.

"Keep going into Chesapeake Bay," Annabeth instructed."I know a place we can hide."

I watched Percy loosen the thermos cap a little more. A burst of wind sent us whizzing around the northern tip of Virginia Beach into Chesapeake Bay. I watched the coast guard boat fade just like the Princess Andromeda. We didn't slow down until the shores of the bay narrowed on either side, and we realized we'd entered the mouth of a river.

"There," Annabeth directed."Past that sandbar."

We swerved into a swampy area filled with marsh grass. Percy hauled the lifeboat at the foot of a giant cypress. Vine-covered trees loomed above us while insects sang in the woods. The air was humid and hot, and steam curled off from the river. I felt myself begin to sweat.

"Come on," Annabeth ushered."It's just down the bank. "

"What is?" I asked.

"Just follow." She grabbed her duffel bag."And we'd better cover the boat. We don't want to draw attention."

We nodded.

After burying the lifeboat with branches, we followed Annabeth along the shore. Our feet sunk in the mud.

"Not a good place," Tyson commented.

I agree.

After another few minutes of walking, Annabeth said,"Here."

Before us, there was a pile of brambles. Then, Annabeth moved aside a woven circle of branches, acting like a door, revealing the inside of the camouflaged shelter. The inside was big enough for four, even with Tyson being the fourth one. The walls were woven from plant material, like a Native American hut, but they looked pretty waterproof. Stacked in the corner was everything you could want for a campout. There were sleeping bags, blankets, an ice chest, and a kerosene lamp. There were also demigod provisions.

"A half-blood hideout..." I looked at Annabeth in awe."You made this place?"

"Thalia and I," she replied quietly."And Luke..."

"So..." Percy began."You don't think Luke will look for us here?"

She shook her head."We made a dozen of safe houses like this. I doubt Luke even remembers where they are. Or cares."

I watched her threw herself down on the blankets and started going through her duffel bag. I sighed, knowing what she was feeling.

"Um, Tyson?" Percy called."Would you mind scouting around outside? Like, look for a wilderness convenience store or something?"

"Convenience store?"

"Yeah, for snacks. Powdered donuts or something. Just don't go too far. "

"Powdered donuts," Tyson said earnestly."I will look for powdered donuts in the wilderness." He turned to me."Bianca! Wanna go with me?"

I nodded."Sure." I turned to them."We'll be right back."

We headed outside.

"Donuts, here we come~" Tyson sings.

I chuckled.

"Monster Donut!" I heard Tyson cried, pointing at a shop that read: MONSTER DONUT

I watched him run towards the shop to buy donuts like he wanted to.

However, it was very odd and strange. A donut shop was in the middle of the woods. It looked brand new, with brightly lit windows, a parking area, and a little road leading off into the forest, but there was nothing else around. No cars parked in the lot. We could see one employee reading a magazine behind the cash register.

How was this even here?

I began hearing this scraping noise. Immediately, I turned to the noise, seeing this thing that had multiple necks, each with hissing reptilian head. My eyes searched for a bush, and I dove into it, pressing my back against it.

"Powdered donuts...donut...donut...donut," I heard Tyson chant.

I looked at the monster and then at Tyson. It seemed that it didn't mind Tyson, probably because he is a Cyclops.

"Bianca?" I heard Tyson call.

Please...

I closed my eyes.

"Probably back with Percy."

I gave a silent sigh. I slowly unclipped my hair clip, revealing my dagger. I held onto it tightly, worried that the monster would come out of nowhere. I didn't dare turn to look for it, so I used my dagger as a mirror.

It was strange. It was too quiet. Not until I heard a twig snap feets away.

"Scatter!" I heard a feminine familiar voice yell.

I turned around, seeing Annabeth. I squatted.

"Annabeth!" I hissed.

She looked at me."Bianca!" She ran towards me, pulling me into a quick hug.

We spotted this green liquid splashed against an elm tree. The trunk was smoking and then, it began disintegrating. The tree toppled straight towards the petrified Tyson. My eyes widened as I noticed the monster was right in front of him.

"What is he doing?!" I hissed."What is that thing?!"

"Hydra," she whispered to me.

We watched Percy uncap Riptide, drawing the Hydra's attention. One of the heads snapped at him. Without thinking, he swung his sword.

"No!" Annabeth shouted.

Percy had already sliced the Hydra's head off. It rolled away into the grass, leaving a flailing stump, which immediately stopped bleeding and began to swell like a balloon. Seconds later, the wounded neck split into two necks, each of which grew a full-size head. It was now an eight-headed Hydra.

What just happened...

"Percy!" I scolded.

"You just opened another Monster Donut shop somewhere!" Annabeth continued.

He dodged a spray of acid."I'm about to die and you're worried about that? How do we kill it?"

"Fire!" Annabeth yelled."We have to have fire!"

"Fire?" I questioned.

"The Hydra's heads would only stop multiplying if we burned the stumps before they regrow," Annabeth explained."Well, that's what Heracles had done, anyway."

He backed up toward the river with the Hydra following. We moved to his left and tried to distract one of the heads. However, one head knocked me to ground, as well as Annabeth rolling next to me.

"No hitting my friends!" Tyson charged in, putting himself between the Hydra and us.

We got up on our feet. Tyson began smashing at the Hydra's heads with his fists so fast. We kept inching backward, dodging acid splashes and deflecting their snapping heads without cutting them off. Suddenly, we heard this strange chug-chug-chug sound. It was so powerful that it made the river bank shake, like an earthquake had begun.

"What's that noise?" Annabeth shouted, keeping her eyes on the Hydra.

"Steam engine," Tyson responded.

"What?"

We ducked as the Hydra spat acid over our heads.

"There! Prepare the thirty-two-pounder!" We heard a familiar feminine voice shout from the river behind us.

"They're too close, m'lady!" We heard a male voice exclaim.

"Damn the heroes!" a feminine voice cursed."Full steam ahead!"

"Aye, m'lady," another voice yelled.

"Fire at will, Captain!" another voice screamed

"Hit the dirt!" Annabeth shouted.

We dove for the ground, hearing a BOOM echoed from the river. There was a flash of light, a ton of smoke, and the Hydra exploded right in front of us, showering us with nasty green slime that vaporized as soon as it hit.

"Gross!" Annabeth and I simultaneously cried.

"Steamship!" Tyson hollered.
