Steadfast (The Lost Fleet: Beyond the Frontier)Book
DEFENDING THE ALLIANCE. The search for two missing lieutenants leads Admiral Geary and the crew of Dauntless on a far-flung chase, ultimately ending at the one spot in space from which all humans have been banned: the moon Europa. Any ship that lands there must stay or be destroyed—leaving Geary to face the most profound moral dilemma of his life. As strains on the Alliance grow, Geary is ordered to take a small force to the border of Syndic space. But what he finds there is a danger much greater than anyone expected: a shrewd and powerful enemy that could finally force the Alliance to its knees.
