I saw this after posting on another by Sleator. I never read Run, but I got on a W.S. kick in middle school, and I loved everything I read by him. I don't remember them all now, but I know they had a huge influence on my reading habits. I still love weird sci-fi novels.

House of Stairs by William Sleater. It's sort of a dystopia. A group of kids are experimented on in this weird building that consists of endless stairs going up and down, and in order to get food and water they had to perform weird acts.

He's not even close to a good source for political or sociological discourse. He thinks he knows a lot, but he's frequently just making stuff up based on vague ideas about Marxism and Post-Modernism, both of which he doesn't understand. His psychology stuff is better (he's a psychologist) but, as others have said, it's mostly outdated, and rather vapid, self-help nonsense. I wouldn't recommend others in that genre because it's a genre that invites and celebrates vapid nonsense.
