When Jacqueline Hyde finds the little glass bottle in Grandma's attic her life suddenly changes. Goodbye clean, good Jacqueline. Hello cheeky, loud Jacqueline Bad.

It's fun at first. Exciting. But then Jacqueline Bad gets into serious trouble. And although she keeps trying to be her old self, the bad side just won't let go...

A darkly addictive fable, truly absorbing.
