In bestseller King's well-crafted tale of possession and redemption, Edgar Freemantle, a successful Minnesota contractor, barely survives after the Dodge Ram he's driving collides with a 12-story crane on a job site. While Freemantle suffers the loss of an arm and a fractured skull, among other serious injuries, he makes impressive gains in rehabilitation. Personality changes that include uncontrollable rages, however, hasten the end of his 20-year-plus marriage. On his psychiatrist's advice, Freemantle decides to start anew on a remote island in the Florida Keys. To his astonishment, he becomes consumed with making art—first pencil sketches, then paintings—that soon earns him a devoted following. Freemantle's artwork has the power both to destroy life and to cure ailments, but soon the Lovecraftian menace that haunts Duma Key begins to assert itself and torment those dear to him.
