Horrible Female Character

So, I'm once again listening to a book on CD in my car. The problem with this one: the main character. She's SOOO annoying. I'm listening to a book called Ladykiller. The main character is a female lawyer but she has no backbone whatsoever. Now, I don't know a lot of lawyers, but I've always been under the impression that they kind of know what the hell they are doing. This character lets everyone walk all over her and doesn't stand up for herself at all. Now, I suppose there could be lawyers like that, but I find it very unbelievable. I find myself yelling at her constantly. Come on people if you are going to write a female character could you not make her more strong-willed? I think the book would have been more interesting (as it would not have affected the story) if she had have shown some bit of a backbone.
