Continuing home from the epic voyage of book 10 in this fantastically popular series of oceangoing novels, Captain Jack and his surgeon/naturalist sidekick Stephen Maturin head from Barbados through the Caribbean across the Atlantic to the Azores and their old stomping grounds in London (where 2/3 of the novel is set). O'Brian builds thumping good tales from the nuts-and-bolts details of sailing ships, Nelson's navy and exotic places around the world.  (ATL04, $14.95)
