The Humming Room

Hiding is Roo Fanshaw's special skill. Living in a frighteningly unstable family, she often needs to disappear at a moment's notice. When her parents are murdered, it's her special hiding place under the trailer that saves her life.
As it turns out, Roo, much to her surprise, has a wealthy if eccentric uncle. Why dose she keep hearing those eerie noises she keeps hearing? And who is that strange boy who lives on the river? People are lying to her and Roo becomes determined to find out the truth.
Despite the best effort of her uncle's assistants, Roo discovers the house's hidden room-- a garden with a tragic secret.
