An Oath is Made

Nadia is a young Daughter of Poseidon at the time the oath of the Big Three is made. In order to protect her from a lethal fate, Poseidon hides her away in stasis, only for the labyrinth to steal her away. Decades later, Percy Jackson is sent on a quest. When he finds Nadia, they learn that she isn't a normal demigod, she's a gift of the river Lethe.
