The Thyme Fiend by Jeffrey Ford is a dark fantasy novelette about a young man who can only prevent seeing visions by eating or smoking thyme. When he finds the skeleton of a missing man the skeleton begins to haunt him. What does it want?
This was a bit of a dark read, but totally worth it. The story of a young boy whose parents help him navigate his demons by making tea and cigarettes with thyme. My favorite part was when the kid's father was teaching him how to roll thyme cigarettes. But then the story sputters to an ending that didn't seem as creative as the rest of it.
