I love the Grand Tour books by Bova, and this one fits right in with the entire saga he has created. The earth has reached greenhouse hell, and Dan Randolph knows that going out into the solar system to harvest minerals for industry is the way to save the earth's economy, and perhaps the earth itself, as well as make Randolph extremely rich. Martin Humphries agrees, but is only interested in the money potential, earth status be damned. Thus begins the race to the Asteroid Belt to claim this treasure, Randolph breaking every rule he can to get there and Humphries doing everything he can to sabotage the mission out of sheer jealousy. Bova manages to write a well-paced, tense journey for these characters, and it sets up well for future volumes in the Asteroid Wars series.
