A song for a stepmom from her stepdaughter?

My father is going to be marrying this amazing woman who is closer to me than my own mother. I am wanting to find a song for a video im in the process of making. The song needs to be something along the lines of a daughter loving her stepmother thou her stepmother didn't have to be there for her. Any help please!!!! <3 This is really important to me and i will take any advice. :)
