House of Stairs chilled me to the very core. Sleator really made the reader feel as if they were trapped in the house of stairs with the characters, left to their natural instincts for survival. It was scary to discover how far our instincts will go, even to the point of harming others. The book could be a definite prequel for 1984, testing just how much the human spirit can plummet before death. The ending seemed a tad unrealistic, but it was a young adult novel, and happy endings are better anyways.
