The thing people are missing is that unless the characters state something that leads us to believe it happens after the HoO, then they aren't spoiling anything. I mean if Percy mentions the war with the giants or something, then yes it is a major spoiler as we would all know he lives. If Percy never brings it up, then the story exists in an undefined period of time between The Last Olympian and The Lost Hero, or sometime after The Son of Neptune. It can't be between The Lost Hero and The Son of Neptune however because Percy was asleep.
