For fans of "The Ark" : 5 of Ben Bova's acclaimed Grand Tour scifi bks

5 paperbacks from Ben Bova's acclaimed 'Grand Tour' (of the Solar System) series. There are about 20 books total in that series, including direct sequels to Mars, Saturn, and Jupiter from this set. Faiirly realistic: unethical giant companies, anti-science religious groups, and eco-warriors scheme and fight for political and economic control of nearly every planet, moon, and asteroid in the solar system, and towards or against scientific discoveries such as search for extraterrestrial life. Worth noting since it can be hard to find, the protagonist in Mars is Native American, and Mercury has a main character who is Japanese (as is one of the unethical powerful companies in the series). If this diversity interests you, please also see the books in my Lupoff "End" listing. Mercury and Jupiter have partially reflective covers. As you can see in the photos, all the books have some wear. Jupiter has a small cover tear, Venus has a small cover crease. Mercury, Venus, and Saturn have small spine creases, and Venus and Saturn have mild page discolorations. 4 are TOR copies, 1 is Ballantine. Overall very good condition, and an exciting saga!
