Okay guys, I need help. One of my friends has recently gotten into PJO and is binging fanfics and has gotten into the Chaos ones but keeps complaining that they are all the same and I know one that is different but I can't remember the name. It's also a HP crossover one. I forget how Percy winds up with Chaos but a time later Voldemort, Kronos and Gaea are rising and working together and the army and the demigods have to head to Hogwarts and Percy makes two cabins and he personalizes all the rooms in the demigods' cabin and he comes in later and asks them how they like it and adds something that he forgot to, I think, Annabeth's room and they are all like "How does he know? Who is he?" And later on the army reveals themselves by free will and then the same day or the next day Percy gets taken and is tortured and everyone is shown this somehow. Then he puts himself in some type of dream state and Luke says something to Annabeth about how she is the only one who can save him and that's how it ends. Does anyone know the name or author of this? Please. I've been driving myself crazy about it.
