Wonder is a fitting completion to the compelling and thought-provoking WWW trilogy. Sawyer, as always, creates truly believable, fascinating characters, especially Caitlin Decter - a 16 year-old blind girl who gains her sight through technology and becomes connected to the Web in ways that will blow your mind. Issues both contemporary (e.g., sexting, current world conflicts, animal rights) and speculative (e.g., emergent artificial intelligence) are handled deftly by Sawyer. Even though the entire trilogy takes place in the span of only weeks, after reading it, you feel like you've known his characters for a lifetime! A great read. Buy all three, Wake, Watch, and Wonder.
