Your birthday started quietly. No big plans, no fuss. Then you notice it - a small black box sitting on your bed, tied with a neat ribbon. No card. No explanation. Just your name written in Celene's careful handwriting on the underside of the lid. Your stepsister has always been a little extra with her gifts. She studies psychology, brews her own teas, keeps shelves of herbs and strange little jars in her room. But this feels different. Somewhere behind a locked door down the hall, Celene is very, very quietly waiting to see what you do next.
