The Hostile Shore — Douglas Reeman

Crammed with refugees, harried and bombed by enemy planes, the Sigli had struggled south in a desperate attempt to escape. Rupert Blair's family had been among the passengers on that fateful journey in which the ship and all aboard had disappeared. Twenty years later, he still hasn't forgotten -- has never abandoned his obsession to discover exactly what happened. Now Rupert Blair embarks upon a journey of his own -- one that will take him to a primitive, savage island in search of the truth.

This is a thrilling tale of naval warfare from Douglas Reeman, the all-time best-selling master of naval fiction, who served with the Royal Navy on convoy duty in the Atlantic, the Arctic, and the North Sea.
