Title: A mirror for observers
Description: In their attitude towards the Planet Earth, the Martians had long been divided into two camps: the Observers, benevolent 'meddlers' in human affairs; and the rebellious Abdicators, who sought the Earth's collapse.

But it wasn't until the extraordinary matter of the Earth-Boy, Angelo Pontevecchio, that the enmity between these two factions came to a definite head.

It started as a contest of wills, waged between two opposing Martians for the soul of a single human child.

And before the end, it threatened all life on both Earth and Mars.
