People often say to me, “I have a terrific idea for a novel! I’ll tell it to you, you write it, and we’ll split the profits!” After I am done kicking them in the nuts, I say, “What is your novel about?”
“Well it’s about a prince, or maybe he’s just a duke, who lives in a country that’s sort of like Switzerland, only with elves. And there are some dragons. And a princess.” At this stage I nod and pass out.
When people ask you what your novel, or movie, or comic is about you must be able to tell them in a brief and exciting manner. A gleaming nugget of concise enthusiasm. One of the oldest stories in Hollywood was the pitch for Star Trek. “Wagon Train in space.” This may or may not be true, but it illustrates succinctly what the show is about. You don’t have to boil it down to four words. A paragraph will do. But your paragraph is just as much an advertisement for your novel as the novel itself. It must intrigue and excite. Once you’re committed to your idea, your first priority should be distilling that hard little nugget of information.
People ask me what my novels are about. Helmet Head: Nazi biker zombies. Whack Job: Spontaneous human combustion and alien invasion. Biker: hard-boiled biker gang crime. Skorpio: A ghost who only appears under a blazing sun. These brief descriptions are not meant as cover blurbs. Cover blurbs are a bit longer and go into more detail. But the nuggets themselves are enough to excite interest. Nazi biker zombies is only three words yet it leaves no doubt as to the nature of the story. Let the reader discover the beauty of your words, the subtlety of your characters’ relationships and wisdom as they read your book. The point is to hook them. The point is to sound like these guys: https://www.youtube.com/watch?v=JQRtuxdfQHw
