Nora Roberts series?

I recently fell in love with Nora Roberts' MacKade brothers series. I read all four of the books featuring Rafe, Jared, Devin, and Shane, and when I went back to look at the cover of the first book, the Rafe and Jared one, I noticed there was a thing that said, "By popular demand, the MacKade brothers are back!" IS there more books with the mackade brothers in them, or is it just these four?|||It's just those four, but they were written quite some time ago as were many of her romance novels AND are being reprinted now that so many other readers have discovered her.|||dunno but I know her next book is called 'Face Of the Past' and it's out in November.
