Correction. Thalia was came in at the end of the Sea of Monsters. But meeting Percy was there. It was a pretty awesome Cliffhanger too.

"-I was holding in my arms the girl destined to be my greatest friend or my worst enemy. 'I am Thalia, Daughter of Zeus.'"

Or something like that. And she was very important.
