The lovely people at Luna Press Publishing have a new non-fiction collection on the way. This one is titled Worlds Apart: Worldbuilding in Fantasy and Science Fiction. I have an essay in it. As you can probably guess, it is about queer animals. You can read a bit about it here.
Obviously there will be many other essays in the book, all of them covering different aspects of worldbuilding, and doubtless most of them better than mine (if perhaps less funny). There are posts about some of them on the Luna Press blog, and more will be coming in due course.
