Tom Swift and the Cometary Reclamation

In the second volume of the Tom Swift Lunar Colony Saga, the action splits apart with Tom working on a solution to a two-headed snake of a problem while Harlan Ames goes in search of answers and a missing woman.

Both the lunar colony and numerous locations on the Earth--California for an extreme example--are so lacking in available water that the time might come when there is a need to evacuate. Both! So, the young inventor sets his sights on finding a way to bring a water-bearing comet within the Moon's gravitational pull so that it might be mined. Of course, how to get chinks of ice to the surface is an altogether tougher matter.

Meanwhile, Harlan finds himself in the mountains of Southeast Asia taking care of an injured woman who doesn't know who she is or how she came so close to death. As he nurses her back to health he finds he is falling in love with her. Even though he knows it will ultimately lead to her finding out who she is and every bit of danger that will bring!
