When she arrives Maynard Castle is still 17 but, just a few days after her arrival, her birthday comes. She doesn't want anybody to notice so, she just sends a letter to her brother telling him about her arrival.
She isn't too much tall and she is thin, maybe a bit skinny. Her hair is long and a sort of dark blonde and her eyes are grey.
She adores the "freedom" that she gets in Maynard Castle but, she sometimes misses her old life in her town.
María adores reading. She had to learn it because she wanted to tell tales to her youngest siblings, to let them know that there are more options than staying around their parents.
She is a good friend of the people who work at Maynard Castle. She has shown good skills with children when she had to take care of Isla Barrie during her first day there.
