The Death House is a horror novel, published in 2016 by English author Sarah Pinborough.
The book focuses on Toby, a young boy living in England at some point in the future. He leads a normal life until he is marked as a ‘defective’ by a simple blood test. He is sent away to the Death House, a boarding school for other children who are marked as ‘different’ by their blood. Everyone is terrified and no one is sure what is going to happen to them. Their lives are monitored by nurses for any changes in their health. Anyone who shows deteriorations is sent away in the night to the sanatorium. They never return.
