Seven Knocks

Three nights before the next seven-minute storm, the homes of Merewick begin to answer with a warning: seven knocks from windows, doors, walls, and floors. Then figures start appearing in the streets. Some are strangers. Others look exactly like people who vanished in earlier storms. And every sighting seems to be moving in the same direction. Atmospheric physicist Dr. Sabine Ketter knows the pattern is changing. The phenomenon is no longer waiting for the storm itself. As Commander Lucan Brett orders a partial evacuation, fear outruns the official warnings, roads lock with traffic, and thousands of residents become trapped inside the district. Investigative journalist Adrian Kell uncovers another danger moving through the chaos: Rainer Colm and Verrick's operatives are hunting a resident who possesses material recovered from an earlier storm site. When the black wall finally reaches Merewick, the seven familiar minutes become a citywide nightmare. Power dies. Dead systems speak. Streets stretch into impossible distances. Doors return people to the rooms they just left. Children disappear within sight of rescuers. And the figures that haunted Merewick before the storm complete a route that points toward a place the investigators have been approaching since the beginning: Dunscar Basin. Seven Knocks is Book 4 of The Seven-Minute Storm, a fast-moving supernatural horror-thriller series by Edrin Vossel.
