Annabeth Chase had gotten a letter. With no return address. Her name, and the Camp Half-Blood address were scrawled in a sloppy cursive. Not her dad. Not her stepmom. Not her stepbrothers. None of them would ever write to her anyway. But she didn't really know anyone else outside the camp. One of her mortal school friends? She hadn't given anyone her summer address.

Was this a prank? No, the Hermes cabin was usually more into things going bang! than joke mail. Annabeth realized that she was stalling. What she really wanted was for this to be from Athena. Her mom. Actual contact, like, maybe a pseudo-normal thing to do, a parent writing to her daughter at summer camp. But Annabeth also realized that it was very improbable. Even after the Second Titan War, and the agreement reached thereafter, it was still was unlikely that a godly parent would actually contact their kid. No, it was still all vague prophecies and unsettling dreams.

Finally, after mulling over this for a minute, the daughter of Athena sliced open the envelope, and a letter fell out, in the same cursive as the envelope. Annabeth winced. Although she loved to read, she was still dyslexic and usually read her books from the Athena cabin library in Ancient Greek, her brain's natural language. And cursive? Even worse. All those loopy letters strung together. But Annabeth managed to painfully read the following letter:

Dear Annabeth,

My name is Luna. I was adopted, and I came with a note from my dad, for when I turned twelve. I read it yesterday. It told me the truth about my existence, about the gods and monsters and everything. But you know that already. There was more. I had a sister, but she ran away when she was seven. Our mom, Athena, came just to comfort my dad, but they ended up having another brainchild, which was me. The letter informed me of the existence of Camp Half-Blood. So I wrote to my sister. You. Hopefully, both you and I are alive when you read this. I ran, too. I'm in Lancaster now, and I know that I'll never make it to Long Island alone. I had to tackle three monsters just this morning, and I can't do this for much longer without help. So please come, Annabeth.

Your sister, Luna
