Perhaps not for me
At first I was going to catechize you using the words 'My father's wife' but as soon as I realized you were talking about a step mother I thought better of it. However, I had some difficulty following exactly what was going on. One minute it looks like everyone is waiting for a speech, then the king runs off, then it looks like the princess is supposed to give a speech, and then she just follows her step mother. And I'm like 'what?"
Read the story now
Overall I'd say it felt like I was reading the second chapter of a story instead of an intro. However, you got some great detail and painted the imagery very well. And having the name Snow White be the princess' idea was a twist I can't think anybody has done before with Snow White, so cudos with that.
