Investigator Oscar Basaran travels to Kidney Island off the coast of Maine to document the negative effects of shadow flicker from wind turbines on residents living near the windmills, but is unprepared for what he encounters from the islanders.
Oscar's research shows that sleep deprivation, light deficiency and ringing headaches brought on by the noise and constant strobe-like effect of the sun filtered through the spinning blades of the turbines brings on hallucinatory episodes for the closest neighbors to the machines. Melody Larson's elderly father nearly chokes to death after stuffing dandelion heads into his mouth. The Granberrys' pregnant cow repeatedly runs headlong into a fence post. Tatum Gallagher mourns her young son who vanished more than a year ago, presumed swept out to sea by a wave while fishing on the rocky shore, but several people claim to see him appear only in the glimmer of the shadow flicker.
Aerosource, the energy corporation that owns the turbines, hired Oscar to investigate the neighbours' claims, but the insurance agent shows no allegiance to the conglomerate, especially after learning a previous employee sent to the island a year before has disappeared without a trace. When Oscar meets former island school science teacher Norris Squires, fired for teaching his students about the harmful effects of shadow flicker, he learns a theory regarding Aerosource that sounds too preposterous to believe.
While it seems the shadow flicker effect has driven some of the island's animals crazy, is it possible it's caused an even worse mental breakdown among the human inhabitants? Or is something more nefarious at work on the island? As Oscar's investigation deepens, he discovers the turbines create an unexpected phenomena kept secret by a select group of people on Kidney Island who have made a scientific breakthrough and attempt to harness its dark power.
