Jonny Baptiste is a reckless teen sent to live with her estranged Aunt Hildie. On the event of her eighteenth birthday, she experiences a radical metamorphosis: a family spell that redefines her called Forevering. When several teen girls go missing at her new school, a mythically feral Jonny goes after the Perpetrator.

Perpetrator

A spate of local disappearances. A hill that may (or may not) be a conduit to the next life. A recluse, living off the grid, who hasn't been seen for years-until one of his high school bandmates shows up with a birthday cake.
