The Ionian Mission: Aubrey-Maturin Series, Book 8 (Unabridged‪)‬

Jack Aubrey and Stephen Maturin, veterans of many battles, return in this novel to the seas where they first sailed as shipmates. But Jack is now a senior captain, commanding a line-of-battle ship sent out to reinforce the squadron blockading Toulon, and this is a longer, harder, colder war than the dashing frigate action of his early days.... A sudden turn of events takes him and Stephen off on a hazardous mission to the Greek islands. All his old skills of seamanship - and luck when fighting against odds - come triumphantly into their own as the story concludes with some fierce and thrilling action.
