The Dreadful Dawn by Kalen Iselt
A family of four is forced to confront a devastating, brutal reality: they are going to lose someone they love. Not only that, but he will try to take all of them with him. A mother and their eight-year-old twin boy and girl face the depths of despair when their father becomes infected with COVID-X, and they must try to survive until dawn. What ensues is a night of terror, as the monster he becomes, a Shadow Seeker, is consumed by rage and bloodlust, with no hesitation to kill the family that he loved and cherished mere hours before.
