I've heard several people asking about naming their books. How do they choose a name? They ask family, friends, and co-workers if the title they picked is good enough. Truth is, most publishers are going to change the title of your book anyway. That's why some authors call their projects 'untitled.'
When Harlequin published my first book, they did this to me. I'd been living with the name Married To A Stranger for so long I couldn't imagine it being called anything else, but Harlequin already had a book with that name. I didn't have a choice. The senior editor told me she had a few titles in mind. I wanted to figure something out for myself, but my editor insisted that we listen to the senior editor.
The book was called Would-Be Wife, a title I still cringe at.
For my second book, I kept the title I chose for it: Borrowed Identity. So sometimes you win, and sometimes you lose. In my opinion, it is better to have a back-up plan going in. Don't just choose one title for your work. Pick two or three just in case the publisher doesn't like what you have. Maybe you'll get lucky. Happy writing.
