It

"To the children, the town was their whole world. To the adults, knowing better, Derry, Maine, was just their home town: familiar, well-ordered, a good place to live. It was the children who saw--and felt--what made Derry so horribly different. In the storm drains, in the sewers, It lurked, taking on the shape of every nightmare, each person's deepest dread. Sometimes It reached up, seizing, tearing, killing ... The adults, knowing better, knew nothing. Time passed and the children grew up, moved away. The horror of It was deep-buried, wrapped in forgetfulness. Until the grown-up chldren were called back, once more to confront It as It stirred and coiled in the sullen depths of their memories, reaching up again to make their past nightmares a terrible present reality"--Jacket.
