it makes sense for it to be dueing an undefined period between TLO and TLH. Having looked at all the comment, i agree that RR wouldnt give away big parts of HoO like that, meaning it is probably set before MoA. Between lost hero and SoA hes asleep, and his shirt is too faded to read in SoA. so it is probably after TLO before percy is taken by hera
