MC is teen boy. Family consists of both parents and at least one sister, maybe two sisters.
Teen boy puts an ordinary coin in his pocket in the kitchen, does not know about the hole in the pocket and coin gets under the fridge.
Some time after the boy has a dream/vision/message from future self(?) about the coin under the fridge and a fire.
Boy gets up about 2am and finds the coin(burns hand) and the dust under the fridge smoking. Saves family and home from a fire.
I think the dream/vision has half/most the family dying.
Mother said she has smelt smoke before.
Father very big on having lists for chores. Says he forgot about cleaning under the fridge/putting it on the list.
Quite sure this story is on SOL and there is much more.
I believe I read in the last two years, but unsure if a new story, a random story pick, or a story about to be archive(hope not).
