Requesting someone to write a story about a 12 year old Princess and her little 9 year old brother trying to escape from a cult (who has murdered their parents). They end up getting caught and they're given the choice to let one or the other die. The princess decides to sacrifice herself for the safety of her little brother so she gets stabbed by each of the cult's members (Jon Snow style) until she finally dies, of course her brother watches the entire thing and is forever traumatized. That's basically the entire summary.
