The short story begins with the prologue: “I began seeing the creatures about a week before Zoe’s visit.” I don’t want to give too much of it away, but the story centers around a mother of a young daughter whose life unravels when she suffers unbearable migraines that cause her to hallucinate as she begins to see creatures. It is the template for a grounded sci-fi story about a mother forced to defend her family against a threat only she can see.
