By the way... my primary project at the moment, I changed the title and even series name a number of times (some of my vacillating can be found in old threads in this section). At first they would each have the same main title, using a different subtitle and year. Then each would have a different T+ST+Y. Then, ditching the subtitle, I came up with a series title... Round and round it went. I even came up with a new system for dating just for the titles
In any case, I say that because you
might be worried that the title is not used as a tag-line in the story... If that's the case, then you definitely must wait till you're done. If not, and you just want a way to refer to it, call it 'Bob' for the time being. That will make everyone really curious
What I will say is:
don't write your story 'around the title.' IOW, allowing the title to dictate how the story runs. It needs to be the other way around, the story dictates the title... hence, you must know the whole story first.
In my needless fretting over my own titles, I ended up instead using what I initially thought in various ways. Some of those subtitles which I really liked, are now chapter titles. That year system gave me a lot of flexibility since now I didn't have it pinned to a real date. My entire series title, is never mentioned until the second novel, and there it is used as a chapter title... IOW, the series theme is not detailed out until roughly 180,000 words into it.
Speaking of tag-lines and the like, I don't use tag-lines
directly. In 'The Abolitionist,' in the last chapter the deuteragonist says: "I'm going to abolish this system, tear it all down..." In 'Lest ye be Judged,' the protagonist discusses what Jesus meant by that with some children, for the deuteragonist's benefit 2/3s of the way in. In 'The Violence of Lambs,' lambs are simply a new type of character... BUT, if I can shorten the series and cram all I have left into a third/final novel instead of 5, that title will become a chapter title, as will the 5th planned novel's (Tecumseh's Land), and 'The Measure ye Mete,' will be the third's title... BUT never stated in the novel as it is mentioned in the same discussion mentioned in the second.
Point being, as I learned... you can spend loads of time on it now, just to discover in the end, it really demands to be called
____________.
Wait till you're deeper into the story if not until it's finished. It will come to you then.
