Yes, I'm stealing lines from Shakespeare to get your attention, but for authors, the question is real. Every book needs a title, and it's sometimes hard to generate one that's both descriptive and alluring. I probably will never pick up a book that has words like rotting or frenzy in the title, though I know people who love that sort of thing. I also avoid mysteries with too-cute titles, usually puns stretched beyond what my English teacher brain can bear. Murder mystery titles should evoke questions about crime, but readers decide from the title (among other things, like the cover, which we'll look at once we get a title) how gory, how depraved, how awful those crimes will be.
My Work in Progress concerns a woman who wakes from a coma to find that her beloved cop husband is dead. The book traces her search for answers about his death and the circumstances surrounding it. Like all my books, the gore level is low and the threat level, while high, isn't bloodcurdling. In my books, no one will ever have their fingernails pulled out, be water-boarded, or get beaten half to death, at least where readers have to watch. I hate that sort of "entertainment." My emphasis is on solving the crime, and while there's plenty of danger, there is no gratuitous violence.
So this book's hero, Tonnie Berndt, is trying to find out what she missed and what really happened to her long-dead husband. Got a great title for a book like that? I have a working title, but I'd love some new ideas.
