It was also the first story I ever wrote, and I often struggled to express what I meant. Maybe the heroine isn’t to your liking. Maybe she isn’t clever enough, talented enough, or strong enough. But I wrote her bit by bit, hunched over my computer every day and working hard for months before finally finishing. This story is my blood, sweat, and tears. Even when I reread it, I can see plenty of flaws, but please go easy on me. Theme:
