Something is tapping insistently against a window. Horribly transformed humans struggle in a world that has changed beyond recognition. An Earthman discovers the power of an alien god. And across the stars, freedom and survival hang in the balance.

Lost Sci-Fi Books 111 thru 115 brings together five imaginative stories by Philip K. Dick, Robert Silverberg, Charles L. Fontenay and Murray Leinster.

Of Withered Apples by Philip K. Dick — Something outside Lori's window refuses to leave her alone. What begins with the faint tapping of an apple against the glass draws her toward a mystery where the ordinary becomes increasingly strange.

Monsters That Once Were Men by Robert Silverberg — They are hideously distorted creatures, twisted almost beyond recognition. Yet beneath their monstrous appearance they are still human, and the truth behind what happened to them raises disturbing questions about who the real monsters might be.

The Guest Rites by Robert Silverberg — Carthule is not the Earthman's god, but the ancient laws of hospitality are stronger than belief. As a guest within the temple, he is entitled to divine protection—even when his presence threatens the temple itself.

The Martian Shore by Charles L. Fontenay — Shaan undertakes an extraordinary journey across Mars, crawling farther than any man should have to go. But the alternative is submission, and some men would rather endure almost anything than bow before tyrants.

Invasion by Murray Leinster — The fighting fleet of the United Nations has been caught in Kreynborg's ingenious trap. With overwhelming power suddenly neutralized, escaping an enemy who appears to hold every advantage becomes a desperate challenge.

From eerie mysteries and alien religions to the struggle for freedom and battles among the stars, Lost Sci-Fi Books 111 thru 115 delivers five journeys into the strange and unpredictable worlds of vintage science fiction.
