Titles are a funny thing. The good ones intrigue book browsers, grab attention, and are memorable. The best ones describe a whole book in a few words. (Some, on the other hand, are not as clever.) And so it’s normal that writers spend a lot of time stressing over giving their manuscript the very most intriguing, grabby, memorable title.
However, from this side of the table, I gotta say, titles are about the least important part of the work I’m considering. Yeah, it’s nice to be catchy in a query. But I’d estimate about eight times out of ten (four out of five, then), a title changes, sometimes multiple times, before it hits shelves. In at least one case, I’ve seen a title change after it was published.
Even if a title doesn’t change, it’s almost always part of a discussion at some point in the editorial process. So when writers and clients ask me what I think of their title, the truth is that I generally think of all titles as “working titles” until they are printed on jackets. It’s not something I focus on in critiques or edits, unless I think it’s wildly inaccurate or misleading. But as part of the query process, it’s not a make-or-break aspect. Make it as good as you can, but also know it may change a dozen times, and then a couple more.
