I would say that, so long as the phrase doesn't bring to mind something that has nothing to do with your book, you should be safe.

As has already been observed, titles are pretty much never covered by copyright laws. Copyright laws cover intellectual property and original ideas, which is why they apply to the contents of a written work, but not to the title. It is possible that titles can be covered by trademark laws, but even then it's almost never for a single piece of work. Typically it would be a series title that's trademarked, but the individual titles are still open.
