In which introductions are made, and the inciding incident takes place (sort of)

Marinia is given two choices- live with her abusive father miserably for the rest of her life, or go as a servant in Eragon and Arya's school for the new generation of upcoming Dragon Riders. Naturally, she choses the latter. Little did she know, the choice would send her into a tailspin of magic, Riders, and an ultumate betrayal. Where do her loyalties lie? Are they strong enough for the upcoming storm?
NOTE: The Inheritance Cycle belongs to Christopher Paolini. If I made any mistakes on the right- giving, plase tell me because this is my first fanfiction, and I don't want Paolini's lawyer running at me with a court invitation.
