Chapter 1: Field Trips and Creepy Philosophy Teachers

Look, I didn't choose to be a half-blood.

If you're reading this right now, and you think you might be one, my advice is: close this right now. Try to lead a normal life. Being a half-blood is dangerous and scary. Most of the time, it gets you killed in painful, nasty ways.

My name is Beca Mitchell.

I'm 16 years old. Until a few months ago, I was a boarding student at Marina Academy, a private school for troubled kids in Portland, Maine.

Am I a troubled kid?

Yeah, you could say that.

My short life, in one word, miserable. But things started going really bad last April. Our class took a field trip to the Metropolitan Museum of Art to look at ancient Greek and Roman stuff.

I know - sounds like torture. Most field trips were.

But Mr Evan, our Latin teacher, was leading this trip, so I had hopes.

Mr Evan was this middle-aged guy in a motorized wheelchair. From his looks, scruffy beard, thinning hair and all, you'd think he wasn't cool. But he told stories and jokes, and even let us play games in class. He also had this awesome collection of Roman armour and weapons, so he was teaching the only class that I couldn't fall asleep in.

I hoped that the trip would go okay. At least, for once, I wouldn't get into trouble.

And as usual, I was wrong. Hooray.

You see, bad stuff happens to me while I'm on field trips. This trip, I was pretty determined to be good.

My friend, Stacie, was sitting next to me in the bus. She was quite the stunner. I'd say if it wasn't for my common sense, she'd already get hit on the moment we went into the museum. She was a leggy brunette, and she would use her body to the fullest, wearing short pants and tops that showed off her cleavage. I made her wear something appropriate for the trip.

Beca: 1, Stacie: 0

Mr Evan led the museum tour.

He rode up front, in his wheelchair, guiding us through the hallways of the galleries, past statues and glass cases full of really old pottery.

It kinda blew my mind that this stuff had survived for about two, three thousand years. They still looked pretty intact to me. Apart from the cracks, of course.

That didn't make sense. Never mind.

Anyway, Mr Evan gathered us around a really tall stone column with a big sphinx on the top, and started telling us how it was a grave marker. Or a stele. For a girl about 12 years old. He was telling us about the carvings on the sides, and I was trying to listen to what he had to say, because it seemed quite interesting.

Only problem was, everyone else around me was talking. Every time I told them to shut up, Mrs Brown, the other teacher chaperone, just gave me the evil eye. Seriously creepy.

Mrs Brown was this Philosophy teacher from Atlanta who always wore a black leather jacket, even though she was already about 50 years old. She had come to Marina halfway through the year, when our last Philosophy teacher had a nervous breakdown.

Ever since she saw me, she'd figured that I was the devil spawn. She would point her finger at me and say, 'Now, Ms Mitchell,' really sweet. By then, I knew I was going to get after-school detention. For a month.

I finally got really annoyed when some guy from the back started talking about the naked dude on the stele. I turned around and said, 'Will you just shut your fucking mouth?'

Everyone was staring at me.

'Oops.' I muttered.

Mr Evan spoke.

'Ms Mitchell,' he said, 'did you have a comment?'

My face was as red as a tomato. I said, 'No, sir.'

Mr Evan just pointed to one of the pictures on the stele. 'Perhaps you'd like to tell us what this picture represents?'

I stared at the carving, and quickly recognized it as one I knew.

'That's Kronos eating his kids, right?'

'Yes,' said Mr Evan, obviously not satisfied. 'And he did so because...'

'Um...' I thought for a second. Then it came to me. 'Well, Kronos was the king Titan, and...he didn't trust his kids, the gods, to not overthrow him. So he ate them up. But his wife hid the baby Zeus, and gave Kronos a rock to eat instead. And later, when Zeus grew up, he made Kronos into throwing up all his brothers and sisters, and so there was this big fight between the gods and the Titans, and -' I was abruptly cut off but Mr Evan.

'Yes, the gods won.' he said. He looked at his watch.

'I believe that you all should go for you lunch break now.'

As I was walking towards the canteen, Mrs Brown materialized in front of me.

'Whoa there, Mrs Brown. Don't need to get all fidgety.' I muttered.

She just confronted me and demanded to know why I wasn't attending her classes in the past few weeks.

The truth was, I had been mixing music in my room. I hated Philosophy anyway.

I smirked at her and said, 'I was posing an important philosophical question. If I don't go to class, would it still suck?'

Apparently that wasn't really the right thing to say at the moment.

'Come with me.' she said, and she pulled me out to the museum entrance.

Stacie was beside me at this point. 'Mrs Brown, where are you taking Beca?' She asked, seemingly worried.

'Just outside for a talk.'
