When the members of the elite Baltimore Gun Club find themselves lacking any urgent assignments at the close of the Civil War, their president, Impey Barbicane, proposes that they build a gun big enough to launch a rocket to the moon. But when Barbicane's adversary places a huge wager that the project will fail and a daring volunteer elevates the mission to a "manned" flight, one man's dream turns into an international space race.
An intrepid interplanetary explorer named Kaiser suddenly comes to his senses after a scouting mission has gone horribly awry -- only to discover that his messages back to the mother ship have become garbled and incoherent, as if someone else was sending them. Who is this mysterious interloper?
A man may be a scoundrel, a crook, a high-phased confidence man, and still work toward a great dream which will be worth far more than the momentary damage his swindles cost.
