On a sweltering summer night in the rundown town of Niagara Falls, New York, the power flickers and goes out. Within 48 hours, the blackout has cascaded across North America. 
For Jimmy Ledanski, reluctant manager of a tourist-trap motel, wounded and reeling from a recent suicide attempt, the outage at first barely registers. For his friend Anna Eisenberg, trapped in Maine at a nursing conference, the minor inconvenience rapidly spirals into a struggle to save her patients in a world without 911, X-rays, or even running water. 
As Anna battles unwinnable odds, her husband and Jimmy join forces to find her. But as society unravels, Anna's heroism and Jimmy's courage begin to fail them…
Drawn from real-world reports by FEMA and the Department of Homeland Security, as well as Lights Outby Ted Koppel,Exit Channel is the story of ordinary people swept up in an all-too-possible catastrophe.
