Going back more to the roots of The Grand Tour, Bova describes how Dan Randolph wrestles control of mining for certain ores in space out from the dominant Soviet empire. This is kind of the forbearance of Randolph setting up his Astro Manufacturing company where he will begin to help explore and colonize the solar system in future novels. Bova's earlier works in this series tend to be better written, so this one falls into the very good category...fun to read.
