The Secret of Loving her Teacher

Meet Addy, an 18-year-old senior who puts her baby sister, Nat, above everybody else, including herself. Her past is not for the light-hearted and she will do anything in her power to ensure that she and Nat don't ever have to go through that again!
She is almost invisible to her peers in school, due to the fact of never attending and making sure there is enough money for her and Nat to have food on the table and heating in their home.
She seems like an open book, confident and full of self-assurance, but what happens when she meets a beautiful woman who seems to see right through her? what happens when this beautiful woman tries so hard to see the real Addy? and what happens when Nat falls down the dark hole Addy has tried so hard to keep her out off?
Can addy overcome her deep-set insecurities and fall into the secret of loving her teacher?
