The Governor of Jamaica organized a splendid 21st birthday party for his adopted daughter, Jessica. However, the best surprise for her came the following day when her admirer, Captain Michael Townsend of the Royal Navy, asked her to marry him. Meanwhile, Captain Flint, one of the most successful buccaneers of the colonial era, decided to take the fortune he had made from twenty years of piracy and retire to his base in Savannah, Georgia, where he would be out of the reach of justice.That’s what should have happened. But Flint was persuaded to raise yet more money through one more crime - more daring and dangerous than any he had previously committed. His men would kidnap Jessica and add her ransom to their pensions. The abduction leads to a desperate chase across the Caribbean and all the horrors of 18th Century life at sea for Jessica and those who try to help her, while Captain Flint himself must face the threat of both the hangman and those within his own crew who plot against him."Tread Carefully on the Sea" is the prequel to the great classic "Treasure Island" by Robert Louis Stevenson. It answers all the questions surrounding the burying of the treasure and what happened to the map upon which X marked the spot. It also reveals how Long John Silver lost his leg.
