John is back with his second book released as a free serialized audiobook. Check out Enemy Lines:
In the near future, an alliance forged by powerful men will challenge the US government for control of secret technology. As their machinations gear up, the true owners of that technology will face a challenge of their own, deep in the asteroid belt. At stake? The future of the human race. ENEMY LINES is a science fiction adventure about conspiracies, spies…and aliens… in a future where the lines aren’t as clear as you think.
