Robinson Crusoe is one of the most famous novels in the English language, although many people find that actually reading it is a fairly tedious enterprise; all that Protestant journal-keeping, all that blather about providence, all that endless marshalling of resources. But the story is a fantastic one, and a true one, too. Alexander Selkirk, a sailor from a small Scottish port town, found himself stranded on Juan Fernandez island for 4 years, and only made it home after being rescued by a passing British vessel. His story, which Daniel Defoe heard second-hand, was soon turned into the famous novel - but the true account, which Diana Souhami tells here with great skill and insight, is far more revealing than Defoe's 'original'. Details of Selkirk's daily life are brought home vividly, as are some of his thoughts and fears, such as his terror of being eaten by the dozens of cats that kept him company on the island. The historical context is well handled, too, and you find yourself learning a great deal about early 18th-century commerce and navigation as you go along. Selkirk's Island deservedly won the 2001 Whitbread Book Prize.
