"The Wager" by David Grann is a gripping narrative that delves into the historical account of a British naval expedition gone awry in the 18th century. The story revolves around the British warship, the HMS Wager, which embarked on a secret mission in 1740 as part of a squadron led by Commodore George Anson. Their objective was to harass and capture Spanish assets in the Pacific, during a time when Britain and Spain were on the brink of war.
