Do you know how often I get queries with the same (EXACT SAME) titles as my clients books, both published and not yet published?
Weekly, at least.
It's especially funny when the book is already out, and the person surely must have at least GLANCED at my website, blog, list of sales on publishers lunch, etc - but they will still query me with books called THE REVENANT or MAGIC UNDER STONE or whatnot.
Like, "I see you like books called THE REVENANT - perhaps you might like my book, THE REVENANT. It's about a revenant."
I... already have a book like that?
But indeed, this even happened before that book was published, and I often thought, welp, this person is going to cry when this book comes out, and think that I "stole their title" -- but in fact, the book has been in the works for two years already, before I ever heard of their query. Sigh.
The thing is -- titles, even great ones, can be come up with by the dozens. I could sit at my desk and write a hundred titles at once - - a handful would be phenomenal, and fully half of them would be FINE and COULD BE BOOKS. (the other ones would be cracktastic and atrocious - and even most of THOSE could be books!)
Some of those probably already exist by someone, at some time in history. So what? Provided your book is different enough, nobody will confuse them.
In the past few months / year the following books have come out or are scheduled soon: ASHES by Ilsa Bick. ASHES by Kathryn Lasky. ASHES by Laurie Halse Anderson. ASHES ASHES by Jo Treggiari. ASHFALL by Mike Mullin. So what? Nobody is irate about it, it's just the zeitgeist. All the books are different, look different, and it is highly unlikely that there will be any confusion for consumers.
What I am saying is - if you have an awesome title, that WILL help your query get looked at more closely. It just will. But titles change all the time - until the book is published, and even AFTER the book is published (check out the Robin Wasserman reissues that came out this month, each one with a new title!) Sooo.... don't stress about it. Putting a crappy or boring title on your query will not help you.
