One dusk in early June, in a town deep in the Balou mountains, fourteen-year-old Li Niannian notices something strange about his town. Instead of settling down for the night, the residents start appearing in the streets and fields. There are people everywhere.

Li Niannian watches, mystified. But then he realises the people are dreamwalking, carrying on with their daily business as if the sun hadn't gone down. And before too long, as more and more people succumb, in the black of night all hell breaks loose.

Set over the course of one night, The Day the Sun Died sets chaos and darkness against the sunny optimism of the 'Chinese dream' promoted by President Xi Jinping. We are thrown into the middle of an increasingly strange and troubling waking nightmare as Li Niannian and his father struggle to save the town, and persuade the sun to rise again.
