Joanne (The Mystery of the Haunted Cottage)

Joanne was created by Annette Billingsley as a main character in her thirty-two book series of Troubleseekers children's novels. She had dark hair and insisted that everyone call her Jo because she was a tomboy.

In a world created by fictional books that Martha Jones had read, Jo was temporarily brought to life by a Ch'otterai. (PROSE: The Mystery of the Haunted Cottage)
