Titles can be hard, but sometimes, just sometimes, they turn out easy.
For some weeks (hmm... actually it's probably months now, though you couldn't tell from the amount of progress) I've been working on something that had just a numeric label (reference to where the seed idea came up in my journal). Two nights ago, while struggling over a major plot problem, I found the solution to that problem and - I think - the title for the story fell out at the same time. I won't share it yet, the story still has a long way to go so things may still change, but I'm very pleased with the possible title. And, meeera, it even has two words! (Sorry, I couldn't resist that small dig - I admit I didn't try real hard
.)
I am afraid, Pulpmeister, that the title might not please you. The title won't, on its own, tell you what the book is - so I'll have to take special care with the cover.
