One thing I'm enjoying is the challenge of writing a book that contains lots of references to death in the first two chapters. The novel is an epic fantasy and death is not one of my central themes, but I needed to establish some character traits early on and forcing my characters to deal with death has given me lots of great options for doing that.
In the next few days I'll put together a "back of the book style" teaser that will reveal more of what my book is about. I guess at that point I should also reveal the name of my book too. :-)
