Captain Singleton

The book tells the story of Bob Singleton, who had been kidnapped as a boy from a good home and grew up with no real home.

He came aboard a ship and eventually ended up being cast on an island with other crewmen.

They managed to get to Africa and about the first half of the novel deals with the company's travel through Africa until they found a port from which they could get back to Europe.

After their return there Singleton became member of another ships' crew and after a mutiny they led the lives of pirates with Singleton as their captain, which mostly covers the last half of the book, finishing in Singleton and a friend being repentant, leaving of their (successful) lives as pirates and returning home in disguise to find a peaceful life.
