The best thing about Robert J. Sawyer's books are that they are truly about something. This book isn't just some excuse to have the internet gain self-awareness ... instead, it's a deep analysis of what makes people (be they geek, bully, computer, or chimpanzee-bonobo hybrid) choose an ethical course over the alternative.
WWW: WATCH is a middle book in the trilogy. In WWW: WAKE (the first book), blind teenager Caitlin Decter gained sight and discovered the existence of a developing consciousness in the World Wide Web. This Webmind, as she calls it, begins communicating with her ... and that's where the second book picks up. Caitlin has to come to terms with suddenly seeing a world that she's only known through touch while also dealling with the fallout from Webmind. Fortunately, she has help from her friends and family.
Less fortunate is the fact that the American government perceives Webmind as a potential threat, especially when it gains the ability to almost effortlessly bypass password security. The government decides that it needs to be terminated, a task that is far easier said than done.
This isn't an unreasonable decision, because it is clear that Webmind (at least initially) lacks any sort of morality at all ... but this, it turns out, is a good thing, because that means it gets to choose how to behave, instead of being guided by instincts which may sway it toward bad behavior. And, as the book makes clear, we all, as conscious beings, have the ability to make this choice. The subjects of morality and ethics, in contexts as varied as teenage relationships, suicide prevention, and personal privacy are explored from the perspectives of game theory, evolution, and religion.
And if you're not interested in any of that brainy stuff about human nature, the story itself stands out as a great read in its own right. I, for one, will definitely make the choice to read the third installment when it comes out ... and look forward to it!
