The beginning is a jarring experience for the mind, but it isn’t overly frightening. There's a depiction of something terrible that has occurred, along with some intense reactions to it. The imagery is truly remarkable. A fresh character seems to have entered the story, bringing the total to two so far. Now it will be interesting to understand their perspectives on what led to the disaster and how they responded. An unpleasant feeling of suspense permeates everything; recollections of earlier times surface, but details about the event itself remain fragmented and difficult to grasp. The presentation keeps you disoriented, leaving you unsure whether you’re seeing memory sequences or full-blown visions. This is a wonderfully made science fiction story, everyone.
