One morning, the residents of a coastal small town wake to discover the sea has disappeared, leaving them 'landlocked'. However, the narrator has been seeing visions of this cataclysm for years. Is she a prophet? Does she have a disorder that skews her perception of time (the 'Dyschronia' of the title). Or is she just a liar? Mills' novel takes contemporary issues of resource depletion and climate change and welds them to one young woman's migraine-inducing nightmares. Her narrator's prevision anticipates a world where entire communities are left to fend for themselves: economically drained, socially fractured, trapped between a hardscrabble past and an uncertain future.
