Under the Moon and the Stars, Fred Uhlman

* Four survivors of a plane crash find themselves on a desert island. They will have to cohabit in the hope of being found.
* But days and weeks pass, and the arrival of help becomes increasingly unlikely...
* A semblance of life is organized, as hope gradually disappears, a sham of life where each person cares only for themselves and walls themselves off in a solitude that nothing can break. Because survival comes at this price.
* There will only be one survivor.
