August's choice for the Metro Book Club is The Ghost by Robert Harris and you can buy it from amazon.co.uk for £1.49 (plus P & P)(conditions apply)
Synopsis: Britain's former prime minister is holed up in a remote, ocean-front house in America, struggling to finish his memoirs, when his long-term assistant drowns. A professional ghostwriter is sent out to rescue the project - a man more used to working with fading rock stars and minor celebrities than ex-world leaders. The ghost soon discovers that his distinguished new client has secrets in his past that are returning to haunt him - secrets with the power to kill.
