Agatha and Sophie had just escaped the School for Good and Evil, how you ask, well Sophie confessed to Agatha in her last dying breath and Agatha had kissed her. That's it, the found her true love and then they turned to dust. But is the end to tale? Well if it is then what the fuck are you doing here? Of course it isn't the end to their tale, and while I do not own the School for Good and Evil, nor do I make any profit from this. I strongly suggest reading the actual series.
