It's Annabeth from the movie. The movie was actually pretty well cast, even if the characters were older than they were in the last book. I was actually looking forward to shipping without the "uhm...12!" aspect? But Percy lost all his snark and likability and was just annoying, and they took most of Annabeth's brain away and pretty much combined her with another female character who's her exact opposite.

Here's my post from after I read the books and watched the movie a couple montrhs ago: http://meganbmoore.livejournal.com/1192223.html
