The Six Swans

I looked at my brother, not believing a word he said. A witch turned him and my five other brothers into swans? Impossible. But then again, I had just seen the obvious evidence right in front of my eyes. I had just watched six swans fly through the window, blow each other off and turn into my brothers! I had to do something.
"How can I fix it?" I stated, to the surprise of my brothers.
"It's too much Soph!"
"Tell me."
"You can neither talk or laugh for the next six years. You must knit each of us a shirt of starwort. One small sound out of your mouth and it will all be for nothing. Are you sure you want to do that?"
"If it means I'll have a family again, then yes."
Suddenly, each of my brothers were surrounding me in a massive hug. And then they flew away, leaving me speechless and wondering what in the world Starwort was.
