When a boy discovers a single-propeller airplane in his closet, he does what any young adventurer would do: He flies it into outer space! Millions of miles from Earth, the plane begins to sputter and quake, its fuel tank on empty.

The boy executes a daring landing on the moon . . . but there?s no telling what kind of slimy, slithering, tentacled, fangtoothed monsters lurk in the darkness! (Plus, it?s dark and lonely out there.)

Coincidentally, engine trouble has stranded a young Martian on the other side of the moon, and he?s just as frightened and alone. Martian, Earthling?it?s all the same when you?re in need of a friend.
