In the Death of Light

"Something bad is going to happen. Something very bad. Something dark."

Harper hoped her mother was just being paranoid. But a week after her passing, the grid collapses. Phones die. The street goes pitch black. The world as Harper knows it shuts down in a heartbeat-except for a single, humming appliance in her kitchen and a mysterious envelope left behind on the counter.

Marked with a drawn lightbulb and a promise to be opened "when the day comes," the letter is no longer a mother's final farewell. It's a survival guide for an apocalyptic blackout that was planned long before the lights went out.
