Girl Parts by John M. Cusick

When David is presented with robot girl Rose by his parents request to treat his dissociative disorder due to him spending all his time interacting and not bonding with people, he doesn't expect her to literally shock him thus making her separated from him after harming him when they're supposed to become friends or more not just have sex like David wants while Rose's programme disallows that to happen before a certain amount of time.

Rose is also a trial robot girl, so when David's parents don't like the changes or lack of in their son, Rose finds herself running into the arms of Charlie, a boy she met after running him off the road when David was driving them home one night after a party.

Rose continues to hide away at Charlie's until a nightmare makes her believe her design company Sakura are after her which leads her to finding Lily, another version of her only a Barbie type version unlike her.

It was a great concept for a book! I love the idea of how robot partners can be developed but how creepy it can be too at the same time knowing you could pick aspects of their personality or design even. I like the aspect of typical sexual norms with girls being Barbie's and males all sex driven as it is quite often true but could've been challenged in the book more as times are ever changing surrounding sexuality.
