When the zombie apocalypse hits and the dead begin to rise, Jonah and his friends are on a class field trip downtown. Panicked, they make a split-second decision to seek shelter in the Overlook, an apartment complex built like a fortress on the edge of town. But as they begin to face the realities of what it will take to survive, they realize that while making the decision of where to run was easy, living out the consequences of that decision may be impossible. From Carrie Ryan, the New York Times bestselling author of the Forest of Hands and Teeth books, What Once We Feared is an original digital short story about facing a world that is forever changed and in which survival means more than merely escaping the undead.
