Two science fiction classics from Ben Bova -- now available together!

Mercury

The planet closest to our Sun is a barren, heat-scorched world. But there are those who hope to find wealth in its desolation. Saito Yamagata seeks to generate power to propel starships into deep space. Astrobiologist Victor Molina is searching for evidence of life. Bishop Elliot Danvers has been sent to keep close tabs on Molina. But all three of these men are blissfully unaware of their shared history, of their connection to the collapse of a geosynchronous space elevator a generation ago, and of the man who now seeks his revenge.

Prometheans

Discover the pioneers whose technologic genius fuels our dreams--and our future. The man who tamed hurricanes and the man whose vision of orbital immortality lost him all he loved on Earth. The day politics, media, and bioengineering met, and the day an assassin took aim on the stars.... Tomorrow belongs to Prometheans.
