Hailey's Shadow by Lori Titus has many unexpected turns and twists, particularly for a short story. We first meet Hailey when she is a little girl, tormented by shadows that speak to her. Time fast forwards to Hailey as a young woman, locked up in an asylum, being interviewed by a man named Adam. He soon realizes there is more to her pyromania than a mental illness, but his epiphany comes at a price.
Titus has this way of frightening readers with monsters, without ever fully revealing the her wicked creations...what she does show you will haunt you long after you finish the story.
You can learn more about this horror master and her terrifying talent in my interview with Lori Titus from June 2015.
