This robot girl, a Companion named Rose, is programmed to help "disassociated" David Sun make real, emotional connections with an "actual" person. An interesting proposal, since with all the internet stuff and texting and things of that nature, it would be easy for teens to get lost and forget what making friends and having boundaries really means. She has this thing called an Intimacy Clock inside her, which tells her when it's okay to touch her at certain points of the relationship. If you touch her inappropriately, she gives you an electric shock. Reward and punishment system.
However, it's easy to forget that Rose is really a machine, not a person. She may look like a girl, but she doesn't have everything that a girl has. *hint hint* When David discovers this, he pretty much dumps her, and she's left heartbroken. Well, the nearest thing a robot could call heartbroken, anyway. Luckily, Rose makes friends with a boy named Charlie, who is a sweet, real guy who doesn't share David's disassociative problem, though he is a little shy and a loner. But he really does care for her, even if she is a machine. In the end, Charlie helps Rose learn to move on and become her own person.
This story was interesting, but I do have a few gripes with it:
1: There's a lot of bad-boy stuff in here. Cursing, drinking, drugs, and all David thinks about is going around the bases with Rose. I mean, it's horrible how much he and his stupid friends treat girls like objects (although in Rose's case, she actually is an object, but still). Personally, I don't go for books like that. It doesn't set a very good example for real teenagers.
2: I wasn't totally convinced that Rose was, in fact, a robot. I don't know, perhaps if you're able to suspend your belief and imagine that there's a company in Japan (Sakora) that makes absolutely perfect androids that think and seem to act human, you can enjoy the story. But she acts and moves too much like a human. She was just too perfect, if you know what I mean. Her thought process had a bit of a technical side to it, but she still seemed to think like a real girl.
3: The ending really seemed to fall flat. Sorry to spoil it for you, but in the end, Rose simply disappears. I have no idea what happened to her. Maybe she was taken away by the Sakora people and decommissioned. Maybe she ran away and started a new life for herself, one without David or Charlie. (I don't see why she couldn't have stuck with Charlie, but then again, she is a robot.) So with Rose gone, both boys get new girlfriends that they're happy with and everyone lives happily ever after. Really John? Really?
In conclusion, I'd say this book may look appealing by the attractive cover, but don't be fooled by it. Your time will probably be better spent with another book entirely.
