The thing is though, is that if Carter thinks Percy looks 17, that means he's either 16 or 17. If he's 16, then it happens right after The Last Olympian but if he's 17, then it happens after HoO. I changed my mind, I agree with Menara. It would make more sense if it's set after Percy Jackson and the Olympians.
