This is the second time I've read this, and while it doesn't grip me with the unbreakable, can't put the book down hold of some of his other works it's a fascinating idea and introduces some concepts the youthful will find useful.

It's not parroted at you, it fits in very well and you do come away with a huge respect for the complexities of Human relationships.
