Cover of the book by Roger MacBride Allen, published by Baen Books, 1988
On the farside of the moon, a massive laser is being constructed, that can hit any point in the solar system, with an devastating destructive force. Whoever controls it, will control the settled colonies of the solar system, and Earth-and so begins the struggle for control of the Farside Cannon...
I got some criticism at the time, about the fact that the moon rocks have no color-but this is a fictional story, and I'm selling books. It's not a technical journal.
