Chapter 1: I Get Kidnapped

Margret's POV

For as long as I can remember I've always lived at Camp Half-blood. Chiron, my guardian, said that I use to live with the Dursley's but I don't remember them. Chiron said that they smelled which is probably true. When I turned eleven I got a letter from a dumb school called Hogwarts. The stupid letter took me ten minutes to read because it's in blasted English. I wrote back, telling them that they could shove their offer where the sun didn't shine.

"You know, that's really rude," Annabeth said to me.

"Yeah, like I care," I said.

Thankfully I got no more letters.

Three years later I was coming back from a quest to bring six demigods, six, to camp. Several of them turned out to be children of Demeter and the others were either children of minor gods and goddess. We have so many cabins it's not even funny. I sat down, after resting and eating some ambrosia, to read my up most favorite book, the Iliad.

"How many times are you going to read that book?" Grover asked.

"As many times as it's still in it's binding," I answered, giving him a look that all of the children of Athena had.

That night, after sing along, I turned in. I was hoping that I wouldn't have to clean the cabin up. Annabeth was leaving bits of stone around that wasn't doing my feet any good. I didn't notice the flashy bird looking down at me. The next day I woke up, not in my cabin, but in a room filled with white beds. Well bed with white sheets on them. I got up and looked out the window and saw that I wasn't at camp.

"I see that your awake," a woman said, "Professor Dumbledore will see you, the password is Bitter Melon."

"Hold it," I said, "Where I and who, am in the name of Hera, is Professor Dumbledore?"

"You're at Hogwarts and Professor Dumbledore is the Headmaster," she said, "Just go to his office on the second floor. You can't miss it."

Oh just great, someone has kidnapped me.

The only problem with finding this office was that I had no idea where I was going. I ended up somewhere that was too high and somewhere that was too low. When I saw an adult I cleared my throat. This man had long black hair, black clothing that looked like something out of the nineteenth century. Nico, would have a laugh if he saw this.

"No students are allowed at Hogwarts while school is not session."

"I'm looking for Professor Dumbledore's office," I told him.

"Well it's not down here," he said.

"Sorry, I got lost," I told him, ignoring the fact that he was being rude. "Can you take me there?"

"Fine," he said, "What's your name?"

"Margret Potter," I answered.

He gave me an odd look and then said, "Professor Severus Snape, Potions Master and Head of Slytherin House."

"Sounds impressive," I commented, though there was no way that I was saying to him that I was a child of Athena. "Do you have an actual degree in Potion making?"

"Sort of," he said, "I got apprentice by Professor Slughorn. After that, I was a Potions Master."

"You must be really smart," I said.

"You could say that," Snape told me, "I don't like dunderheads."

"Sounds like some of my cousins," I said, "Though not Piper! She's been around snotty kids all her life and can't stand them. Of course she's got snotty kids as her siblings; one of them is her personal nightmare name Drew."

Snape said nothing and then I said, "Can you show me where this Headmaster's office is."

"Like I said, I'll show you," Snape told me and I followed him out.

Even though I wasn't a fan of being here I couldn't get away from how huge this place was. There were tons of arches, which I knew held the ceiling up. I gazed at everything and jumped a foot in the air when a man moved.

"Magic," Snape said, "They all do that."

"Oh dear Hera Lou would freak out," I said.

"Don't tell me, another cousin."

"Correct," I said.

"You have too many of them," he remarked.

"Yeah, don't remind me," I said and then we found the gargoyle the woman told me about. "Bitter Melon."

The gargoyle moved aside so that I could pass.

"See you later, Miss Potter," Snape said.

"Thanks, for showing me the way," I told him and then I was gone.

Professor Dumbledore turned out to be a man that I would have to watch out for. He went on about some man name Sirius Black that was coming after me. When he told me that he was placing me in third year I had to draw the line.

"I have no formal training and yet you want to place me in third year," I said, "Are you mentally insane?"

"You're the Chosen One, you'll do fine," he said.

"Um, no I won't," I countered, "Let's be logical here. I have no training, I have no idea what to do, and yet you want to put me in third year."

"Once again, you'll do fine," he said, "Now tonight is the Sorting and I've already gotten your things. You can stay in the Library until the train arrives."

I had a bad feeling that he wasn't going to let me go.

When I got to the Library, which took me even longer to find, I sat down and thought over what I could do. It was clear that this man wasn't use to be told no and he wasn't about to let me return to Camp. I closed my eyes and mentally called out for my mother.

"I'm here, child," Athena said.

"I have been taken against my will," I told her.

"I know that and Zeus is not happy," Athena said, "However, you're going to have to stick it out until we can get some help for you. Grover is beside himself with worry."

"I can imagine," I said, "What am I suppose to do about sacrifices?"

"I'll have the West Wind drop you off a jar of Greek fire," Athena told me, "And trust that Severus Snape guy, he's my son."

I was shocked and then I asked, "Does he know?'

"No, but I'll visit him when the time comes," Athena said, "Be careful and don't let anyone know that you're a demigod. Also, don't listen to what people are saying about Slytherin, their not a bad house."

"I will try," I vowed and then Athena cut the connection.

Severus's POV

I had been shocked, and surprised, that Potter was inside the castle. I had heard that Dumbledore, that idiot moron, had said that he was going to get Potter here for her third year. I hadn't even seen the child except for that one time that I had seen the dead body of the woman that I loved. Now seeing Potter she looked nothing like James or Lily and I wondered if Dumbledore had made a mistake. She seemed interested in what he did for a living and had asked him where the Headmaster's office was.

Now we were setting at a pre-term meeting, Dumbledore smiling as though he had gotten an early Christmas Present.

"As Severus knows Miss Potter is here."

"I can't believe that you kidnapped her," Professor Sprout said.

"It was the only way to make sure that she would get here," Dumbledore told her, "Now that she's safe, with us, Sirius Black won't be able to get her. Now when term ends she'll be sent to live with the Dursley's. She's never going back to where she was."

"I'm sure she's happy there," I told him.

"Happiness is not what I want," Dumbledore told me, "Her ability to kill the Dark Lord is."

I had a bad feeling about this.

A/N: Hope that you enjoyed this chapter. Also, Margret is going to be getting some help in ensuring that Dumbledore doesn't send her to the Dursley's, who have no idea that she even exists.
