Girl Parts by John M. Cusick
Super-rich David and his friends are into the cyber-world--in fact, they watch, laughing, as a classmate commits suicide online.
David's parents decide to socialize their son through a perfect robot girl who will be a companion with built-in timing for appropriate levels and times for kissing, touching, etc. ...if you go too fast, you recieve an electric shock!
David receives Rose, falls for her, finds out that all these Japanese robots are not really anatomically correct, then loses her when she seems to develop a mind of her own.
Charlie, on the other hand, can't afford a robot but appropriates Rose after she leaves David. Because she is a robot, he feels he can talk to her--and after all, she is programmed to listen well. He can even find someone to make her a "real girl." The "relationship" can't last, however. The company will not allow their expensive robot to roam free--too late for David to realize that he really does care for Rose.
Fun and quirky, this book falls short of the mark on character development. The appeal will be to reluctant reader boys, and while the "robot with a heart" is appealing, the inventive idea just barely saves the book from being a shrug.
Recommended for 8th grade and up.
