^^Why dont you like Annabeth???

^^^And I think a big one people have in mind is the sacrafice at the doors of death. Maybe Annabeth will be the one that has to stay behind, but it could as likely be anybody else since Percy has trouble giving up anyone he is close to. But I just have this feeling that it won't be at the doors of death. Maybe someone will have to be sacraficed to bring peace between the greeks and the romans. I don't have any idea how that would play out, but i'm just trying to think of posibillities.

It could have something to with the fight with the giants in Greece. I don't know, I just really have a feeling it won't be at the doors of death because that just seems too obvious to me. But I might be wrong, and I proabably am.
