Search Worlds Without End

Where is the border between life and non-life, between living organism and lifeless rock? This is the story if a man and a woman--both scientists, both dedicated to peace--who first discovered the living Water and knew they had found the great and terrible secret of the source of all life...

...Great because their discovery opened out into a future of opportunity and abundance.

...Terrible because the living Water intensified men's inherent tendencies for good or for evil. As individuals, they were free to drink the living Water...if they dared. As scientists they faced a graver problem. What would the world make of their discovery: another Hell...

...or another Eden?

The Americans have a top-secret project - called the Black Planet - which they plan to send up 10,000 miles where it will rotate on its axis and, by means of its instruments, bring back a record of what is happening all over the world.

A new and strange element called Maggellarium is discovered. A piece the size of a pill is sometimes so heavy that a man cannot lift it from the floor. At other times it is so light that it climbs the wall and pushes through it to disappear at an angle. It is controlled by the position of Sirius, the Dog Star.

These discoveries unleash jealousy amongst the scientists, sabotage, international incidents, and United Nations intervention.

Santa Felicia Island is a Guided Missile Base isolated by the strict regulations of military security. Here are gathered the theorists and technicians who will build tomorrow's weapon. Within days, or perhaps hours, the international arms race may be decided by what these men accomplish. But something is seriously wrong.

A simple scientific demonstration produces an "impossible" result.

A strange tremor passes over the island, and Time itself is suspended for a moment. Two creatures penetrate the island's defences--a man and a woman both more powerful and more gentle than ordinary humans.
