An interesting twist I've encountered on Chapter Titles is having a quote precede a chapter rather than a title. In books like "This Alien Shore" they add a depth and flavor to the novel's world as well as add a commentary on, rather than spoiler for, the following chapter. They also seem to create a universal undercurrent to the themes of the novel as a whole.
edit: that was weird... I was trying to post this in the thread "chapter titles yes or no" and if somehow posted here... not sure what that's about...
