Tom Swift and the Space Battering Ram (The Tom Swift Lunar Trilogy)

What happens when a pair of accomplished authors already working on their separate Tom Swift adventures get together to create an all new TOM SWIFT adventure? A great story from two imaginations. Tom Swift discovers that something is causing collisions to happen far out in the asteroid belt. While it is curious, it is seemingly not of any real concern. But, a comet believed to have last visited our solar system fifty years earlier is spotted coming inbound… but it is early. Very, very early! The mathematics show that last time it passed harmlessly when the Earth was on the other side of the Sun, almost one hundred eighty million miles away. This time, however… it is thought to become a near miss situation until the unthinkable happens. A totally unexpected change to its course means it's now on a collision course and it looks like only Tom can find a way to avoid catastrophe. That is, IF he has the time! Complicating things are a pair of megalomaniacs bent on colonizing the Moon with kidnapped Asian islanders while destroying life on the Earth. They have also taken Tom's chief of Security prisoner, but Tom knows nothing of this until it is almost too late!
