The Jar of Futures: Fantasy or Sci-fi

The mind-jar fell from her hands and cracked on the floor. The midwife stared, horrified. She waited for it to break, for the child's future to fall out, to spill across the floor and be squandered. She held her breath. The jar rocked slightly from side to side, but the crack didn't widen. She couldn't see a single piece of sand that had spilled out. And yet, she didn't trust it. She stooped and lifted the jar carefully, oh-so-carefully, and carried it with her into the birthing room.

Notes: It's more a future-jar than a mind-jar. Child obviously grows up under a cloud of worry that at any moment, something catastrophic--. And then Something Bad happens to the entire community, and Child is the one who basically "mends the crack before it breaks" after figuring out that could mend the future-jar so that it was no longer in danger of shattering at any minute. Could even be alien anthropological sci-fi, though I was thinking of as being more modern, set in an isolated mountain community somewheres--or could work as African community, too. I am an equal-opportunity pillager of culture, yes, I am!
