The 3rd book in the Saga: The Emperor Shangri-La died trying to attack the Earth in book 1; the Empress-his twin sister-died trying to attack Tom Swift in book 2. Now, it seems the very Moon on which they built their Shangri-La colony of slaves is on the brink of being attacked by the ground under their feet. Harlan Ames, former Swift Enterprises Chief of Security has been the Administrator of the now free colony but is getting anxious to take his twin children back to Earth. Their safety may depend on it; their mother was the much hated Empress! But, something bad is happening inside the Moon. He hopes his old boss can figure things out before it is too late. In the meantime, he leaves his children in the care of Lola "Grandma" Reyes at the lunar colony while he heads out to see if there is anything to discover at the former "Master's" ruined fortress in the Philippines. It is a race against time to see if clues can be found to help avoid a catastrophe.

In this hardbound second installment of the Lunar Trilogy (Tom Swift and the Space Battering Ram was part 1) an environmental disaster hits California at the same time the lunar colony-now free of the tyranny of the Masters-is facing a crisis of their own, and it seems a single solution needs to be found for both. At the same time, Harlan Ames ventures to Tibet in search of answers about the Empress and where she might have crashed her evacuation spacecraft. What he finds will turn his world on end and nearly ruin the now-free colony on the Moon. With his own troubles, Tom must find a way to mine water from a passing comet and bring it to the Moon and down to the Earth safely and quickly before people start to die. As it is, people are leaving the state as if it is becoming a new dustbowl. The inhabitants of the lunar colony don't have that luxury. Will Harlan's search and Tom's projects succeed? Or, with they intersect with disastrous consequences?

The Oxford bookseller and publisher John Henry Parker (1806-84), a supporter of the Tractarian movement and a friend of Cardinal Newman, was also a historian of architecture, whose two-volume Glossary of Terms Used in Grecian, Roman, Italian, and Gothic Architecture is also reissued in this series. In 1851, he published a volume on English domestic architecture from the Norman Conquest to 1300 by the antiquary Thomas Hudson Turner (1815-52), and on Turner's death he completed the second volume, on the fourteenth century, himself. Both volumes are highly illustrated with line drawings and plans. Volume 1, after an introductory chapter about pre-Conquest buildings, discusses architectural plans, features, building materials and techniques of the twelfth and thirteenth centuries, and gives examples of surviving buildings, from grand to modest, all over England, as well as reproducing documents throwing light on the painting and decoration of medieval buildings.
