For generations, Quentin Marsh's family has seen its share of tragedy, though he remains skeptical that their misfortunes are tied to a centuries-old curse. But to placate his pregnant sister, Quentin makes the pilgrimage to Point Pleasant, West Virginia, hoping to learn more about the brutal murder of a Shawnee chief in the 1700s. Did one of the Marsh ancestors have a hand in killing the chief -the man who cursed the town with his dying breath?

While historian Sarah Sherman doesn't believe in curses either, she's compelled to use her knowledge of Point Pleasant to uncover the long-buried truth. The river town has had its own share of catastrophes, many tied to the legendary Mothman, the winged creature said to haunt the woods. But Quentin's arrival soon reveals that she may have more of a stake than she realized. It seems that she and Quentin possess eerily similar family heirlooms. And the deeper the two of them dig into the past, the more their search enrages the ancient mystical forces surrounding Point Pleasant. As chaos and destruction start to befall residents, can they beat the clock to break the curse before the Mothman takes his ultimate revenge? . . .
