When the story begins, Janie is a fun-loving, silly, dreamy 15-year-old girl. She yearns for romance and excitement, and attempts to make herself seem more exotic by altering her name on school papers (i.e. Jayyne Jonstone). She is very close with her parents, and perhaps a bit spoiled. Physically, her most striking characteristic is her head of unruly red hair.
As the story's plot develops, Janie becomes fixated on her kidnapping and stops being (and having) fun. She is too self-absorbed to recognize and fulfill the needs of the people she loves. Her inner turmoil causes her to lash out at those around her. Inwardly, she is judging herself harshly for being a selfish daughter who could be bought from her biological family with ice cream. However, the experience ultimately causes her to realize how great her love for her parents is, and what a wonderful life they have given her.
