This is funny because as I was writing this, our Rumba, which we call Sparky, and which frankly, is a useless robot in its blind and random - and very inefficient - seeking out of dirt (I cannot recommend that either!) got stuck on something and I had to stop what I was doing, and go rescue it! Some day we will get it right, but we're nowhere close yet.
I had issues with this novel, and while for most of the reading of it, I was looking on it favorably, it went to hell in a hand-basket in the last third. In the end, there's one major reason why I cannot rate it positively: the whole book was about companionship and healthy relationships, but all of this was betrayed when the author made it quite clear that the only value a woman has is her vagina and her willingness to allow a man to penetrate it. It's particularly ironic then, that for this, the woman is destroyed!
The story was a bit improbable to begin with - that a corporation was allowed to sell life-like female robots as companions to teen boys. Yes, it was in the end, a scam, but the robots were real, and very lifelike and very female - except for the fact that they had no primary sex organs. Not that this would make her any less female, but it is nevertheless how women are viewed in the western world, and this author buys right into it and does so completely and unapologetically.
Rose is a one-of-a-kind advanced gynoid. We're not told why she's one of a kind. She's bought by David Sun's rich father. When he finds out he cannot penetrate her and leave his mark of ownership, he ditches her and she tries to decommission herself by jumping into a lake. She's rescued by school nerd Charlie. The dip in the lake confuses her programming somewhat, and detaches her from her wireless link to her corporate "owner" (how that works since David's dad actually bought her is a mystery, but some of this book is quite confused).
Rose and Charlie start building a relationship, but rather than have that blossom and develop, the author takes the low road and has some chop-shop fit Rose with a vagina so she and Charlie can have sex. After that she's evidently of no more use. the company reclaims her and presumably destroys her, and Charlie takes up with a human female, never giving Rose a second thought. This is entirely the wrong message to be sending to young readers: that women are commodities and disposable. They're already thought of that way and it needs to change. This book does nothing to help. The ending betrays the whole story that has gone before, and I cannot recommend this as a worthy read.
