That's who are - or more accurately, who is - writing this.
Are you sure you want to tiptoe out of your mind's little castle and step on thin air?
Dangerous minds... etc. derived from a quote from the wonderful and wonderous fly by night by Frances Hardringe (dangerous books, gunpowder books, books that could burn away the castles of the mind and change the color of the sky....). All credit to her. But it's my mind that you really don't want to blow sparks into, because you'll go boom and I'll still be here, I always am. Always. Forever and a day.
