From Publishers Marketplace, more cupcake fiction on its way:
Beth Ciotta's THE CUPCAKE CLUB series, in which each story features its own hero and heroine, recurring characters and the antics revolving around The Cupcake Club - an eclectic group of town folk intent on making a difference in the world via cupcakes, to Monique Patterson at St. Martin's, in a very nice deal, in a four-book deal, for publication in 2012, by Amy Moore-Benson at AMB Literary Management (World).
Separately, there is also a series of children's books called The Cupcakes Club.
