In the face of an Atlantic hurricane, a boatload of mis-matched crew and passengers find themselves aboard a life-boat and must pit their strength against the rigours of the open sea. Tension mounts both inside and outside the rescue vessel - the desirable Synolda is forced into the arms of a man who knows her past and uses that knowledge. A man with hatred in his eyes - a hatred that can only be satisfied with blood.

There is mutiny and murder before the unrelenting Sargasso weed entombs them all. But suddenly land is sighted - land unmarked on the chart, concealing further, unimaginable horrors.

Dennis Yates Wheatley (1897-1977) was an English author whose prolific output of stylish thrillers and occult novels made him one of the world's best-selling writers from the 1930s through the 1960s. His Gregory Sallust series was one of the main inspirations for Ian Fleming's James Bond stories.

Born in South London, he was the eldest of three children of an upper-middle-class family, the owners of Wheatley & Son of Mayfair, a wine business. He admitted to little aptitude for schooling, and was expelled from Dulwich College. Soon after his expulsion Wheatley became a British Merchant Navy officer cadet on the training ship HMS Worcester. During the Second World War, Wheatley was a member of the London Controlling Section, which secretly coordinated strategic military deception and cover plans. His literary talents gained him employment with planning staffs for the War Office. He wrote numerous papers for the War Office, including suggestions for dealing with a German invasion of Britain. During his life, he wrote more than 70 books which sold over 50 million copies.
