Are there any "what if" fic where Burdock's fatal mine collapse never happened?
I was just thinking about how that would change things. Katniss' heart wouldn't harden. She wouldn't become burdened. She'd go on singing. She'd be loving. She'd let herself fall in love. Possibly with Peeta, even before he's reaped. And she would still be brave enough to volunteer for Prim. (Of course, Katniss would never have taken tesserae so the arrangement of slips would be different, but let's handwave that away).
In some way she might be less prepared. She'd have spent less time in the woods overall and certainly less, if any, alone. But the time she spent there she'd be getting more advanced lessons from her dad.
And the similarities with Lucy Gray might be even stronger if she sings for her reaping and interview.
If you don't have fic rec, let's discuss what you think would be different or stay the same?
