What waits quietly in the shadows at night? What is under your bed, always out of sight? Have you ever heard strange, creaking noises in the night? Have you ever wondered what causes those sounds? Lucy Dungston has always done so. Until one morning, Lucy discovers that all the adults have vanished - as if they have dissolved into thin air. Chaos erupts as the children in Lucy's town run amok. It's a mess. It's madness. For most children, it's fantastic! But Lucy wants to uncover the truth. Lucy lost her father not long ago, and she is determined not to lose her mother as well. She will bring her back - and nothing will stop her... except perhaps the creaking.
