Knock Knock by S.P. Miskowski (1st Chapter)

At the center of S.P. Miskowski's novel-length fairy tale are three restless girls, best friends stuck in the backwater of Skillute, Washington in the late 1960s. Their neighbors and families are petty or poor or both. They warn the girls not to wander into Skillute's dense forest; something evil lurks there, people say. The girls are not convinced. During a playful oath, they wander too far into the woods. Their mistake unleashes a malignant spirit that terrorizes Skillute for the next fifty years.
