Don't go near the house, whatever you do. It wants the lonely, the lost, the vulnerable. It wants you.

Tanya keeps having bad dreams about the old stone house around the corner from Coal Hill School--and a girl trapped there, screaming and terrified. When Tanya and her friends go to investigate the strange house covered in cobwebs, they stumble onto their own worst nightmares come to life. But there is a presence haunting the house that is even more powerful than their individual horrors. A presence that may not want to let them go...

In spite of the danger, Tanya is determined to free the mysterious girl in the house. But they are running out of time--the house is scheduled for demolition. With the help of their teacher Miss Quill, Tanya and three other kids prepare to fight their nightmares, and whatever other monsters they hear scuttling around in the walls. But how can they fight against monsters that are supposed to exist only in their dreams?
