i read the section on "titles" and you mentioned there is a "formula" for suspense, thrillers and the like. what is the formula?
I don't think there's a formula like in algebra, plug in this and you'll get this, but if you look at a shelf full of thrillers or suspense titles, I think you'll soon begin to see a pattern of titles like: Bad Blood, The Cold Room, Still Missing, Edge, Skin, Torn Apart....
In other words, simple, chilling, and kind of scary. There's nothing too descriptive in a thriller or suspense title (typically).
When you choose a title, choose one that represents the tone or voice of your book. In other words, does your title itself convey a mood, or tell a bit of a story to the reader?
