The Titan's curse part 4

[Jake]

Lady Artemis, God of the hunt, summons Bianca into her tent in the forest. She talks with her about joining the hunters. In order to do so, Bianca must swear an oath and vow never to love or be involved with men. Men are not allowed to join the hunters, which means she would leave her brother Nico with Percy and his friends. Bianca accepts the offer and is part of the sisterhood. Percy is shocked at Bianca's decision. Percy, Grover, Thalia, and the hunters must now go to camp half blood with the help of Artemis's brother, Apollo.
