Agadir, Morocco, 29th February, 1960 - a motley cast of colourful characters in search of adventure, romance, and refuge descends on the elegant Hotel Saada, but their lives are suddenly jeopardized by a devastating earthquake.

The earthquake lasted just twenty seconds. But twenty seconds is long enough to destroy the Hotel Saada and change forever the lives of its guests. Winston Graham's Tremor is a novel of love and greed, wickedness and courage, and of one man's search for himself.
