When a young woman foresees her community’s catastrophic doom, she must choose between keeping a solemn promise – and telling the life-saving truth.

Who did she make the promise to? Why do they want her to stay quiet? How is the promise connected to the catastrophic doom?

I see the story as her promise not her struggle. The way it is positioned doesn't the balance the drama. Sacrifice is choosing between two equal values. Saving lives or keeping a promises is not balanced. The secret must be huge so it needs describing.

If the promise is just a way of introducing stakes and a ticking clock for her rehab, there may be a better way.

Strong not string....sorry :-)
