When night-shift cashier Bea discovers a receipt printed with a message that wasn’t there before—You will read something that feels like a door—her quiet life inside a 24-hour convenience store begins to warp. What starts as a strange glitch soon becomes a conversation between her, a graduate student named Carlo, and the mysterious printer that seems to know what will happen next. As their written exchanges grow into something alive, fiction and reality start to blur, and their story begins writing them back. In a city where words can predict, command, or erase, Bea must decide what to believe—the logic of ink or the faith of love. A Sky Built of Receipts is a haunting, lyrical exploration of authorship, identity, and the fragile line between creation and control—a novel that asks what happens when the act of writing becomes the act of being written.
