My novel that my agent is currently shopping around has gone through a series of titles. Initially, when the novel was in short story form, I called it "Nature of Choice." It was without a title for a long time while I made it into a novel. I settled on Perception. This title earned me an audience with a couple agents and a contract with my current one. I don't know that I was a fan of the title and my agent wasn't either. For a very short time I called it Injected, only to be shot down again by my agent. Then it took on Uploaded for quite awhile and the title grew on me. But as I worked through another series of revisions with my agent, he wanted a better title before we sent it out to publishers. We brainstormed and came up with Infinite Worlds which I'm not a fan, but I realize it's a place holder. I'm sure if it does get picked up by a publisher (crossing my fingers, praying, wishing on a star), they'll want to change it again too.
A member of my writers group suggested, Undergrad God. I really thing that one was my favorite.
