Who is Jade "Jadie" Ekdahl from Ghost Girl: The True Story of a Child in Peril and the Teacher Who Saved Her and what is their importance?

Jadie Ekdahl is one of the children in Torey's special education class. She is the daughter of Mr. and Mrs. Ekdahl. She is also the older sister of Sapphire and Amber Ekdahl. When Torey first meets Jadie, it appears that Jadie's biggest problem is her elective mutism. On her first day of working with Jadie, however, Torey persuades Jadie to begin talking. Jadie is very interested in Torey's work with mute children. She asks Torey often if these children talked to Torey about their problems and if Torey believed what they had to say.
