Time has always been considered a line. Linear. Logical. Immutable. But this is not a story about logic. It is about love. About memory. About choices that bend the fabric of time, even if only for an instant. Somewhere between science and emotion, between a falling star and a beating heart, lived Aster — a woman made of equations and silence. And Riven — a man made of secrets and possible futures. They met not because time allowed it… but because love decided there was no line that could separate them. This is not a book about the end of the world. It is about what is left when everything ends: a fold. a name. a feeling that resists time. Welcome to line 319-Z. Or as some prefer to call it… the line where love learned to stay.
