Zoë Nightshade

Zoë Nightshade was the former lieutenant of the Hunters of Artemis, before her death in The Titan's Curse.

Zoë Nightshade was one of the Hesperides (the youngest of so ) and therefore, the daughter of Atlas. Her main role in a prophecy was the one that drove The Titan's Curse:

Five shall go west to the goddess in chains

One shall be lost in the land without rain.

The bane of Olympus shows the trail,

Campers and Hunters combined prevail.

The Titan's Curse one must withstand,

And one shall perish by a parent's hand.

She perished by a parent's hand. While withstanding a serious blow by Ladon (which happened to be poisoned) and was brought to an end when Atlas (her father) threw her against a wall.

Trivia

 * She talks in a very old-fashioned way.
 * She seems to have been born before 1886, as evident by her statement that she "had been driving since automobiles were invented." This leads Percy Jackson to wonder if she had a license, and what her birth date said.
 * It is later revealed that she is over 2000 years old.
 * She dislikes Thalia Grace.
