Another title question...I can almost see you rolling your eyes?

I like the meaning behind a red moon, but don't call it that. It is too close to New Moon, unfortunately. A Moment and Forever is cool, but sounds more like a YA romance. Shades of Gray is good too, but sounds familiar. I also like Jagged, but again, sounds familiar. I do really like When the Cards Tell a Lie. If I saw that on the shelf I would pick it up and read the back. I would say go with what you like the best, though. It's your book! Write and create for yourself, not what other people want or like.
