Alex Colt. Cadete espacial

Alex Colt is an orphan who lives in a shelter. One day he slides down a sliding chute but never reaches the ground. His body disappears from earth and reappears aboard an alien spaceship. Alex is conscious of this when he sees the moon flying by the hatchway, like a sign on the road informing you that you are leaving your village. He hardly gets to see them from the other side of the glass cylinder in which he travels.
