This popped up on my trading site and I had heard good things of Gill McKnight, though not this particular book.
I now know why ;) It's incredibly flat and soulless. It is billed a romantic adventure, but really, there's not a lot of romance in it. There is a lot of talk of sex and being horny (that word must be used a gazillion times in this novel), but feelings aren't really palpable. The characters are flat and sometimes caricature-like (especially the evil ex) and didn't engage me at all, thus I couldn't really bring myself to care about the lead romantic pairing. The dialog is supposed to be funny, but really often is just crude, I think the story is supposed to have a sitcom-like feeling to it, but some of the situations are just unbelievable and thus not funny to me.
I wonder how much my dislike of this book, set in the movie-biz, stems from just having read Kallmaker's Stepping Stone, who manages to describe the business with well-rounded characters that are anything but stereotypical.
