The action-filled sequel to two of the greatest adventure novels of all time - Alistair MacLean's 'The Guns of Navarone' and 'Force 10 from Navarone'.

Alistair MacLean's gritty heroes from Navarone are not dead, and definitely not forgotten. Mallory, Miller and Andrea, the surviving commandos from 'Force 10 from Navarone' are sent on operation Storm Force: a perilous mission through the Pyrenees to disable the greatest threat to the success of the D-Day landings - the 'Werwolf' U-boats.

The Storm Force have less than six days to locate the submarines and destroy them. With communications insecure they must operate outside normal channels, cut off from any back-up. Their Basque guides declare it mission impossible.

But they have never worked with Mallory.
