Brain Thief is marketed as a science fiction novel, but it's also a mystery novel. Some readers have even said it should be called a mystery with science fiction elements, because the mystery element is key to its appeal. I would agree, though I think the gonzo part is important too: the thirty-foot fiberglass cowgirl riding a rocket really catches the spirit of the book.
It's hard to categorize. That's not such a great idea from a marketing perspective (you'd think I know better), but there are a group of readers for whom this is perfect. I don't want to mislead anyone, so I'm working hard to find and inform this group of people: people who like well-constructed mysteries, and find an SF element a plus, and like humor and sly observation.
If you are one of them, drop me a note and help me! How do I get this book in the hands of people like you?
