I just finished listening to Verner Vinge's book "Rainbows End". There were some things about this book which were very difficult to follow in audio, perhaps reading it would be easier. Overall it was an interesting portrayal of life in the near future when personal technology has become as useful as shoes and eyeglasses. But I have to say the ending of this book was a tremendous disappointment. It's not a spoiler to say that The Rabbit is one of the most intriguing and important characters of any book I've recently read. Vinge showed his genius in creating Rabbit as one of the heroes, or was it an anti-hero? It's hard to classify.
So why after all this effort and success would Vinge leave the character unresolved at the end of the book? We learn nothing about Rabbit. He is simply not there. We don't know if he is dead or alive, a winner or a loser. Vinge may intend on writing a sequel, but he still should give some hints. In the end we are left to guess as to the core of Rabbit's essence. Saying more would perhaps give away a spoiler.
Vinge's vision of a technological life is encouraging. HIs vision of secret personal messaging is excellent and shows that the next evolutionary step after IM is still just a conversation. And his ideas of what would happen to old people whose diseases were suddently cured is inspiring.
But I can't get past the question "What happened to the Rabbit ??"
Interesting note, SF Reviews did not even mention the Rabbit.
