Leo Greeley, a down-on-his-luck history teacher, inherits his "eccentric" great-aunt Hester’s Victorian house in Ohio. He discovers it’s no ordinary home: it physically manifests echoes of powerful emotions as temporary phenomena. Guided by Hester’s cryptic ledger and a pragmatic mail carrier, Leo learns to curate this weight of the past. From ghostly toaster crumbs to a decades-old silence of unsaid grief, he must audit these echoes to find harmony. In balancing the town’s hidden heartaches, Leo discovers his own purpose, transforming from a reluctant heir into the dedicated keeper of the profound, human music of what is felt, but not always heard.
