Thalia Grace

Thalia Grace is currently a Hunter of Artemis, the assistant leader, after the deceased Zoë Nightshade. She is a daughter of Zeus and Beryl Grace, and she was formerly a pine tree. She is the "half-sister" of Jason Grace, son of Beryl Grace and Jupiter. She had a quarrel with Zoë before, but in the end decided to honor her instead of turn away. It was a big decision, letting the one that will be in the prophecy (Percy Jackson) save the world.
