I have a few more ideas for in-story concepts that might make titles. What do you guys think of these?
- The Unspoken Covenant
- The Lie Sublime
- Tearing the Shroud
I was just glancing over this and it struck me that "The Sublime Shroud" sounded interesting, and though it probably wouldn't work for your book, it made me think that one of the best things a title can do is intrigue, and this often happens when you get words that you wouldn't expect to find together; you can't figure out what they might mean except by reading the book.
So to take your examples:
The Unspoken Covenant - OK, you have an agreement that's unspoken, I've understood that, no need to read the book, next!
The Lie Sublime - A perfect or beautiful lie, that's easily comprehensible, next!
Tearing the Shroud - some kind of shroud gets torn, as they do, next!
But ...
Eating the Shroud - WTH????? Now I need to know what on earth that title can possibly mean, so I examine the back cover a bit harder, flick through a few pages, and hopefully doing so will get me caught up in the story.
OK, so it might not be the best example, and obviously the title would need to make sense in the context of the story, but maybe you should look at titles that might provoke a reaction rather than summarise the novel?
