A New York Times Bestseller: A young woman descends into a demonic madness—only to discover that it’s not simply in her mind

Aspiring model Allison Parker finally moves into her dream apartment: a brownstone on Manhattan’s Upper West Side. But her perfect home quickly turns hellish. The building is filled with a cast of bizarre tenants, including a reclusive blind priest, who watches her day and night through an upstairs window. Eventually, Allison starts seeing things and hearing strange noises from the empty apartment above hers. Before long, she uncovers the building’s demonic secret and is plunged into a nightmare of past misdeeds and evil that knows no bounds.

From New York Times–bestselling author Jeffrey Konvitz, The Sentinel, which was adapted into a feature film starring Ava Gardner, Cristina Raines, and Chris Sarandon, is classic horror at its best.
