In the first book of Robin Wasserman's trilogy, we are presented the question of what it means to be alive. Lia has been injured so badly in an accident, she won't survive, so her parents make the decision to place her into a mechanical body. Is she actually still alive, or not? In the second book in the series, more and more people are beginning to believe that these people in mechanical bodies are not really alive, and there is a group called "The Brotherhood" which is trying to prevent further mechs from being created.
In this, the third book, the stakes are still higher. Mechs have been declared property, with no real penalty for their destruction. And The Brotherhood is doing worse things.
As a whole, I'd have to say I found Wired much more interesting than Crashed. The book seems to have a clearer purpose, and while we lose much of the questioning about what being alive means, it's overshadowed by the basic need to stay alive and to continue to stay alive, something in question throughout much of the book.
There are a couple of major revelations, one which finally explains the fathers words near the end of the first book, and one that, at the time, while perhaps horrible, seems otherwise unimportant for much of the book. Zo finally becomes a fully drawn character in this volume. We never really knew her before, and what we did know of her, we rarely liked. But here we finally get to meet her and judge her on more reasonable terms.
The book moves very quickly and is a quick read, and I very much enjoyed it.
Until the last few pages.
The ending of the book is abrupt, and barely foreshadowed. (If foreshadowed at all.) All of the sudden, the story becomes something entirely different than what we've been reading. It would be correct to say that it is a happy ending, but it is so unexpected that it doesn't fit any of what came before. It also seems to be an easy way out of the dilemmas which the characters are in -- everyone will be safe and happy due to this ending, but it's an entirely unsatisfying end to the series.
If you enjoyed the first two, then go ahead and read the third. But be aware that the ending doesn't really fit the rest of the series. (And, by the way, doesn't leave much room for another book to be written, either.)
