Enough theoretical discussion, let's look at what I've come up with:
Obviously, the name of our book is "The Wind-up Child." It features genetically-engineered, super-powered teens who are being used and sold as slave mercenaries. "The" and "Child" makes perfect sense, but "Wind-up" is a little more open to interpretation. It might mean "Old time-y technology," or (as it turns out) it might be more metaphorical, representing something give an input and it follows a predetermined course. There's a definite sci-fi aspect to our tale, so I wanted to move people away from the "Old time-y" interpretation and stress the futuristic nature of the story. I also wanted the word "Child" to be charged with a sense of tension, danger. The uneven x-height and inconsistent ends of the letters help contribute to this ... or at least that's what I intended. I'll be curious to hear peoples' reactions to this logo.
