Charlotte I by Parker

I haven't been able to figure about a few things about Charlotte I. First of all, where's Charlotte II? The story is credited to Parker and "?????." Anyone know the identity of the mystery author?

In any case, this is the story of Charlotte, a young and innocent hotel clerk who is blackmailed into sexual servitude. It's well-written (as is most of Parker's work) and is a damn exciting read. Definitely worth your time.
