Hello guys, I haven't written the first actual chapter yet, and the summary space wasn't big enough, so here's the summary.

In the Kingdom of Ferryport Landing, lives Sabrina, a poor teen. She lives with her sister, Daphne, and her parents. As a poor family, Sabrina has to work all weekdays at the May Estate. The May's aren't the kindest people, but she needs the money. One weekend, the king sends out a message, inviting all ladies between the ages of fourteen and eighteen to an interview, where they will be judged as a good or a reject. Out of all girls, one-hundred will be selected, to go to a princess academy, to learn how to be noble. Then two years later, at a final ball, the prince will visit and pick his bride. Sabrina is called to go. Meanwhile, murders and attacks on the kingdom and the royals are being issued. What will she do?

for the people who have guessed, it does hold essense from both The Goose Girl by Shannon Hale and Princess Academy by Shannon Hale.
