What's wrong with Poseidon? We haven't heard anything significant about him since the Last Olympian. I thought Poseidon might show up in the Mark Of Athena to talk to Percy or something. Rick makes it sound as if the sea god disappeared from the world like Percy. Its pretty strange that a caring god-dad has stayed very silent for a long time unlike the other gods.
