Lynn Pierce was the mother of Jasmine Pierce and the girlfriend of Roy. Her ex-husband — Jasmine's father — had left the family when their daughter was just a baby.
Like Roy, Lynn thought that Jasmine was strange because she had no friends and talked with her imaginary friends, and felt that Jasmine spent too much time alone. Unlike Roy, however, Lynn was concerned as well as unnerved by Jasmine's behaviour, whereas Roy merely hated anything unusual or that made Jasmine happy.
Roy was killed by the Fairies in 2007 at the garden party celebrating the five-year anniversary of their relationship. She was then left alone when Jasmine was taken by the Fairies to their "Lost Lands". Having lost her partner and her only child on the same day, Lynn suffered an emotional breakdown.
