The Forbidden Child (Percy Jackson love story)

Leah Edens is a demi-god, she has known her whole life but she has no clue who her godly parent is. Normally she would stay in the Hermes cabin like the rest of the undetermined half-bloods, but for some reason she got her own room in the big house.

Leah never knew who her father was either; she was dropped off at the camp borders right after she was born with only a crescent moon pendant, Leah was basically adopted by Chiron, even Mr. D is nice to her.

Anyway, she only finds out who her godly parent is when Percy Jackson arrives in camp with her best friend Grover Underwood.
