Prologue:

"Hey! I'm not always sarcastic! Sometimes, I'm asleep."

Estelle is seven years old and Sally and Paul's daughter. Or at least, that's what she's been told.

She's actually Percy and Annabeth's daughter. They had her at 17 and Annabeth didn't want to raise her, so she decided to hand Estelle to Sally.

But what happens when the truth comes out? When Estelle is wanted back?
