''House of Stairs'' was written by Creator/WilliamSleator in [[TheSeventies 1974]]. One of his earliest works and considered to be one of his best books to date.

America in the distant future is a CrapsackWorld with little room to live, hardly any food to eat and even less to go around for the disadvantaged. Five sixteen-year-old orphans are abducted and relocated to a house filled with nothing but sets of endless staircases, a landing with running water and a flashing machine that forces them to play mind games for food. None of them know the reasons behind being put in the ''House of Stairs'', and the machine forces them to perform acts of escalating cruelty upon one another. Their escape hinges upon being able to divine what they can about their circumstances and the motives of their captors.
!!''House of Stairs'' provides examples of:
* BlankWhiteVoid: The setting of the House itself is mainly a big white void filled with stairs that lead nowhere.
* ConvenientlyAnOrphan: All five of the main characters are orphans. Justified in that [[spoiler:the government specifically took teenagers from orphanages so]] they wouldn't run into as many legal/missing persons issues.
* CrapsackWorld: The food that comes out of the machine is actually cooked meat, but most of the teenagers describe it as "brown pellets" because none of them, save Blossom, who had come from a wealthy background before being orphaned, had ever even seen or heard of eating meat before.
** Lola tells the others how, after stealing a car that breaks down, she had to keep ducking back into the stopped vehicle for a breath of filtered air so she wouldn't expire from the pollution before the highway police rounded her up.
* {{Dystopia}}
* DesignatedLoveInterest: Averted and even lampshaded by the author. [[spoiler:Peter and Lola get out of the building,]] and they're walking together and holding hands. One of them then spends a paragraph thinking on how not all inter-gender relationships are sexual. {{Anvilicious}}, perhaps, but probably necessary given how common this trope is.
* OntologicalMystery: None of the characters know how or why they were taken to the house of stairs, or what the whole purpose of them being there might even be.
* ShownTheirWork: Sleator clearly did at least basic research on psychological conditioning.
* SuperSoldier: [[spoiler:The ultimate purpose of the mental conditioning the House provides]].
** Either that, or [[spoiler: Super ''SecretPolice'']]. The experiment cultivated ''cruelty'' rather than strength, after all.
* UnwittingTestSubject: The characters [[spoiler: are part of an experiment]].
* YouAllMeetInACell: These are the circumstances of the book in a nutshell.
* {{Zeerust}}: The depiction of the food machine as a giant metal box with flashing lights and beeping sounds is quite retro by today's standards.
