Poseidon First Demigod Daughter

Y/n L/n came to camp half blood when she was eight and got claimed two days later by her father, Poseidon. She is in a relationship with Clarisse La Rue, daughter of Ares. They've been together for two years and they are the "it" couple in the camp, courtesy of the Aphrodite cabin. Everything seems to be the same until Percy Jackson came to camp and immediately Y/n knew who his father was. Since her father told her when he visited in her dreams.

Once Percy is claimed as Poseidon's son, she takes him under her wing and helps him out with controlling his water powers, all while going on a quest to find Zeus bolt that was stolen that Zeus blames them for.
