Nico di Angelo & the Princess of Darkness

Chapter 1: Mystery

I never meant to find out about Rose Valentine. But considering she had been a camper at Camp Half-Blood I was surprised that there were no stories about her at camp. Rose Valentine was a Daughter of Aphrodite with blond hair and brown eyes that changed to different shades of Gold-Brown. She was 17 when she died. She was on a quest with Luke Castellan.

I was in the Big House attic cleaning out some of the old souvenirs to return them to the gods or what not, when I had found a picture of three people, two boys and one girl all about 16 years old. One boy I recognized Luke, Percy's old enemy turned good at the last few minutes of his life but this was before he had his scar so he looked like a completely different person, he was standing behind the other boy and the girl. The boy was holding the girl around the shoulders like they were good friends. The girl was blond with brown eyes and pink lips she was very attractive.

Why this was in the attic I had an idea. Back in the old days when campers went on quests frequently the three people who went on the quest would get their picture taken together right before they went on their way, I guess Luke didn't want any reminders of his quest, so I put the picture aside and made a note to ask Chiron about the picture.

But then another picture caught my eye, back in the old days the campers who returned from quests would get another picture taken to show how much the campers had changed over the quest. This picture was of Luke and the other boy but the girl… she was absent from this picture.

I continued looking through the attic and found a Camp Half-Blood bead necklace with four beads on it I looked at the beads closely the first one was a sword inside a red heart. The second one was a Pine tree a bead I recognized immediately because I had seen it on Annabeth's bead necklace. Percy had told me it was the year Thalia had been turned into a pine tree as she was dieing. The Third was a Greek trireme on fire. The final one was a Centaur in a prom dress.

If this was among the things in the attic then it had to belong to someone. The girl from the picture maybe, I looked at the picture again and this time I saw the necklace, four beads, so she had been at camp a year before Luke and Annabeth. Did Annabeth know who this girl was?

I put the god's things in one pile and then the girl's things in another pile. There was her Camp Half-Blood necklace, the quest pictures, a journal, a photo album, and a knife.

It was very similar to Annabeth's but it had a heart engraved in the hilt. I don't know why I wanted to look through these things but something in my gut told me that I needed to. I put the god's things in a box and filled out a slip to send it to Mount Olympus. I took the other things to the Hades cabin. I looked at the photo album first the first picture was of that mystery girl.

She was about 11 she had a sword by her side. What a eleven year old girl was doing with a sword I had no idea. The next picture was of six people. The boy from the picture of Luke's quest companions was in this picture he had a bow in his hand and a quiver of arrows on his back, the girl was in the picture a sword by her side, they both looked about thirteen.

A man about thirty was in the picture holding a small girl of about four and she had a dagger on her belt.

The man had a sword by his side to and I could tell that he was the father of the girls. The other two in the picture were women one about thirty she had her hands on the boy with the bow and I saw the resemblance, his mother no doubt.

The other woman was about twenty-five and was standing next to the man. I could see both of their left hands and I saw matching rings on them.

His wife and the girls step mother no doubt because she looked nothing like ether of the girls. But then I looked at the man and the other women in the picture and I saw something that made me do a double take.

The girls father had the same blue eyes as the boy's mother it didn't take long for me to figure out what it meant, the man and women were brother and sister. I took a look at the boy and recognized his sandy blond hair I looked at his eyes and realized that they were blue but not the same blue as his mothers, add the bow and arrows and I guessed he was a son of Apollo.

I looked at the girls, the older one looked almost exactly like the younger one but I could see one difference the older girl had brown-gold eyes and the younger girl had green-brown.

I then realized with a start that the four year old girl in the picture had to be a half-blood but if her sister had been here why had this girl never been to Camp Half-Blood either she had been killed or, maybe, she didn't want to come here.

I looked at the dagger and recognized it as a similar dagger that the four-year-old girl had attached to her belt but the difference was that this dagger was longer in the blade.

Just then someone knocked on my cabin door I put the things quickly under my bed and went to the door.

Percy Jackson the son of Poseidon said "Grover wants to see us, something about a powerful half-blood" I nodded and walked out of the cabin and to the forest with him.
