Usually when you think of foreshadowing, you think of a plot device that is used in mystery or suspense, but as more and more authors are writing series books, I am discovering that it is being utilized more in the romance genre.
In the mystery genre foreshadowing is used typically as a precursor to pending doom and build suspense for the great pièce de résistance. I remember racing through the pages of Tom Clancy’s Patriot Games desperate to find out what was going to happen to Jack Ryan’s family.
In the romance genre it can be used for a mystery within the story, however many authors use it to create desire for the next book in the series. It is like a movie trailer broadcasting coming attractions. It can be about a character and a potential relationship or it can be a plot device. But no matter what it is about the author creates a hook for the reader and gives them a reason to buy the next book.
