When Joe and Louise O'Connor move into their new home in the quaint coastal village of Bayberry, Long Island, they feel as though it is a dream come true.

When the disappearances continue and residents are savagely attacked by unknown predators, Louise alone is willing to undertake the task of revealing Bayberry's secret. At the same time she learns something about herself, something that puts her at risk both for her safety and her sanity.
