The Unknown Shore

Blurb

The Unknown Shore is a novel published in 1959 by Patrick O'Brian. It is the story of two friends, Jack Byron and Tobias Barrow, who sail aboard HMS Wager as part of the voyage around the world led by Anson in 1740. Their ship did not make it all the way around the world, unlike the flag ship. The novel is a fictionalised version of actual events which occurred during the Wager Mutiny.
Some reviewers feel that the midshipman Byron and the somewhat unworldly surgeon's mate Barrow are prototypes for Jack Aubrey and Stephen Maturin, who appear in O'Brian's Aubrey–Maturin series set in the Napoleonic Wars.
