Rusty Nailed - Alice Clayton

I really loved Wallbanger but that book didn't need a sequel at all. And now, it's a (at least) four book series? I didn't need to know about every single character that appeared in Wallbanger. I'll probably read them anyway if Rusty Nailed is good but I wish Wallbanger would have remained a stand alone.It was a very good on it's own.
