Dauntless (The Lost Fleet, Book 1)

After a hundred years of brutal war against the Syndics, the Alliance fleet is marooned deep in enemy territory, weakened and demoralised and desperate to make it home. Their fate rests in the hands of Captain Black Jack Geary, a man who has been presumed dead but then emerged from a century of survival hibernation to find his name had become legend. Forced by a cruel twist of fate into taking command of the fleet, Geary must find a way to inspire the battle-hardened and exhausted men and women of the fleet or face certain annihilation by their enemies.
