There's been a more than decent William Sleator rundown posted recently on a site called adamcadre.ac. As with many things on the web, I've no idea who wrote the piece or why it's necessarily there. Just the same, it's remarkably insightful, especially when you consider the author's take on Sleator's work, both old and new. And though some would classify this particular author as YA, I know for a fact that my library has Intersteller Pig and Singularity firmly in our children's collection. For anyone who has ever searched in vain for worthy sci-fi children's books (you'd be amazed how often schools require their kids to read some), this article is a must read.
