Oh Percy3 I liked this quite a bit. It was nice to see Annabeths point of veiw holding up the sky. I like that she thinks herself slightly dilusional for believing she can see and hear her friends. And the implied Percabeth3 xD

One little thing I noticed in the second paragraph, "her exhausted frame shakes with exhaustion." is a little redundant. Finding a word to replace exhausted would greatly improve the sentence.
