Stephen King's N. (2010)

A field in Maine holds a disturbing arrangement of seven stones, a crude circle with a single, horrifying Eye at its center. The structure exerts a palpable, malevolent pressure on the landscape. For the man known only as N., whose life is governed by the strict rituals of his obsessive-compulsive disorder, this place has become an inescapable focus. His compulsions are no longer a private struggle but a desperate defense against the entity that dwells within the stones, the same force implicated in another man's recent suicide. The line between psychological illness and supernatural predation has completely dissolved. The field waits, patient and watching.
