There is no point in approaching this novel worrying about a plot: it’s just an old-fashioned romp.
Ne’er-do-well Seth Weinstein for some reason is about to be married to the gorgeous, successful Tina Clark, high-powered Washington attorney, daughter of billionaire Mike Clark. The wedding is to take place at the Ritz-Carlton in Key Biscayne. So much for the story.
The rest of the book is a series of mishaps, compounded by amusing incidents complicating the wedding event and personal relationships. The author means to keep the reader laughing minute after minute, and often succeeds. Great literature it is not intended to be, just a very amusing read. And so it is.
